Phosphorus-halogen bond elongation and autoionization in a Cl,Br,I-series of N-heterocyclic phosphane halides with saturated backbone: diazaphosphorinane vs. diazaphosphorinenium salt
Halide exchange reactions of PX3 (X = Br, I) and the known 1,3-di-tert-butyl-2-chloro-1,3,2-diazaphosphorinane (1) gave the bromide (2) and the iodide (3). The new compounds have been characterized by elemental analysis, IR and NMR spectroscopy. H-1, C-13 and P-31 NMR spectroscopic data give strong evidence for a non-ionic behaviour of 1, 2 and 3 in solution. Single crystal X-ray structure determinations of 2 and 3 for the first time allowed for a detailed comparative study of the solid state structures of a Cl,Br,Iseries of NHPXs with aliphatic backbone. Like in 1 in 2 a partially flattened cyclohexane-like chair conformation with the nitrogen atom substituents in a diequatorial orientation and a substantially elongated covalent bond between the phosphorus atom and the axial oriented halogen atom is found. Neither a covalent P-I bond nor a preferred chair conformation is present in the solid autoionization product 3 that should be labelled phosphorinenium iodide instead of P-iodophosphorinane. Its solid state structural parameters are in line with the expectations for a [-N(tBu)](2)>P+-fragment with high diazaphosphaallyl cationic character. (C) 2020 Elsevier Ltd. All rights reserved.
Electric Literature of 4286-55-9, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 4286-55-9.
