Sodium triorganostannylalkylsulfonates R₃Sn(CH₂)_nSO₃Na (I, R = Me, Ph, n = 2,3) are obtained by reaction of triorganostannylsodium with sodium haloalkylsulfonates or propane solution in liquid ammonia. I can be converted by ion-exchange in the free sulfonic acids R₃Sn(CH₂)_nSO₃H which are of limited stability and undergo cyclocondensation reactions with formation of the cyclic triorganotin alkanesulfonates II (R = Me, Ph, n = 1, 2).

Gorsline, Bradley J. published the artcileC-H Alkenylation of Heteroarenes: Mechanism, Rate, and Selectivity Changes Enabled by Thioether Ligands, SDS of cas: 55788-44-8, the publication is Journal of the American Chemical Society (2017), 139(28), 9605-9614, database is CAplus and MEDLINE.

Thioether ancillary ligands have been identified that can greatly accelerate the C-H alkenylation of O-, S-, and N-heteroarenes. Kinetic data suggest thioether-Pd-catalyzed reactions can be as much as 800× faster than classic ligandless systems. Furthermore, mechanistic studies revealed C-H bond cleavage as the turnover-limiting step, and that rate acceleration upon thioether coordination is correlated to a change from a neutral to a cationic pathway for this key step. The formation of a cationic, low-coordinate catalytic intermediate in these reactions may also account for unusual catalyst-controlled site selectivity wherein C-H alkenylation of five-atom heteroarenes can occur under electronic control with thioether ligands even when this necessarily involves reaction at a more hindered C-H bond. The thioether effect also enables short reaction times under mild conditions for many O-, S-, and N-heteroarenes (55 examples), including examples of late-stage drug derivatization.

Lange, Stefanie C. published the artcileEfficient and Tunable Three-Dimensional Functionalization of Fully Zwitterionic Antifouling Surface Coatings, SDS of cas: 55788-44-8, the publication is Langmuir (2016), 32(40), 10199-10205, database is CAplus and MEDLINE.

In order to enhance the sensitivity and selectivity of surface-based (bio)sensors, it is of crucial importance to diminish background signals that arise from the nonspecific binding of biomols., so-called biofouling. Zwitterionic polymer brushes have been shown to be excellent antifouling materials. However, for sensing purposes, antifouling does no suffice, but need to be combined with the possibility to efficiently modify the brush with recognition units. So far this has only been achieved at the expense of either antifouling properties or binding capacity. Herein the authors present a conceptually new approach by integrating both characteristics into a single, tailor-made monomer: a novel sulfobetaine-based zwitterionic monomer equipped with a clickable azide moiety. Copolymerization of this monomer with a well-established standard sulfobetaine monomer, results in highly antifouling surface coatings with a high, yet tunable amount of clickable groups present throughout the entire brush. Subsequent functionalization of the azido-brushes, via e.g. widely used strain-promoted alkyne azide click reactions yields fully zwitterionic 3D-functionalized coatings with a recognition unit of choice that can be tailored for any specific application. Here the authors show a proof-of-principle with biotin-functionalized brushes on Si₃N₄ that combine excellent antifouling properties with specific avidin binding from a protein mixture The signal-to-noise ratio is significantly improved over traditional chain end modification of sulfobetaine polymer brushes, even if the azide content is lowered to 1%, thus offering a viable approach for the development of significantly improved performance of biosensors on any surface.

Scott, Philip J. published the artcilePhosphonium-Based Polyzwitterions: Influence of Ionic Structure and Association on Mechanical Properties, Synthetic Route of 55788-44-8, the publication is Macromolecules (Washington, DC, United States) (2020), 53(24), 11009-11018, database is CAplus.

This manuscript describes a synthetic strategy and structure-property investigation of unprecedented phosphonium-based zwitterionic homopolymers (polyzwitterions) and random copolymers (zwitterionomers). Free radical polymerization of 4-(diphenylphosphino)styrene (DPPS) provided neutral polymers containing reactive triarylphosphines. Quant. postpolymn. alkylation of these pendant functionalities generated a library of polymers containing various concentrations of neutral phosphines, phosphonium ions, and phosphonium sulfobetaine zwitterions. The zwitterionic homo- and copolymers exhibited significantly higher glass transition temperatures (T_g) and enhanced mech. reinforcement in comparison to neutral and phosphonium analogs. These changes in T_g and mech. properties were attributed to nanoscale morphol. domains, which formed due to electrostatic interactions between zwitterionic groups, as revealed by X-ray scattering and broadband dielec. spectroscopy (BDS). BDS revealed increased static dielec. constants (>25) for the phosphonium zwitterionomers compared to ionomeric or neutral analogs. These high static dielec. constants for the solvent-free polyzwitterions supported their stronger polarization response in comparison with polymers containing neutral phosphines and phosphonium ions, and these interactions accounted for morphol. differences and enhanced mech. behavior. This work describes a versatile strategy for modulating electrostatic interactions with tunable mech. properties for an unprecedented family of zwitterionic polymers.

Progress toward durable and energy-dense lithium-ion batteries has been hindered by instabilities at electrolyte-electrode interfaces, leading to poor cycling stability, and by safety concerns associated with energy-dense lithium metal anodes. Solid polymeric electrolytes (SPEs) can help mitigate these issues; however, the SPE conductivity is limited by sluggish polymer segmental dynamics. We overcome this limitation via zwitterionic SPEs that self-assemble into superionically conductive domains, permitting decoupling of ion motion and polymer segmental rearrangement. Although crystalline domains are conventionally detrimental to ion conduction in SPEs, we demonstrate that semicrystalline polymer electrolytes with labile ion-ion interactions and tailored ion sizes exhibit excellent lithium conductivity (1.6 mS/cm) and selectivity (t₊ ≈ 0.6-0.8). This new design paradigm for SPEs allows for simultaneous optimization of previously orthogonal properties, including conductivity, Li selectivity, mechanics, and processability.

Eight N-alkyl-N-sulfopropylaniline derivatives were synthesized and assessed as water-soluble H donors for the spectrophotometric determination of H₂O₂ in the presence of peroxidase. The Na salts of N-ethyl-N-sulfopropylaniline (I), N-ethyl-N-sulfopropyl-m-toluidine (II), and N-ethyl-N-sulfopropyl-m-anisidine (III) are recommended. They have excellent water solubilities, and the optimum pH range for oxidative condensation with 4-aminoantipyrine in the presence of H₂O₂ and peroxidase is 5.5-9.5. The absorbances of the resulting chromogens are 2-3-fold higher than that achieved with PhOH. The molar absorptivities of the chromogens with 4-aminoantipyrine are 41,300 (I, γ_max 561 nm), 37,400 (II, γ_max 550 nm) and 27,900 (III, γ_max 540 nm). Calibration graphs for the determination of H₂O₂ in the presence of a control serum are linear for 7-40 × 10^-6 mol H₂O₂/L.
