Wood, Devin P.; Guan, Weiyang; Lin, Song published their research in Synthesis in 2021. The article was titled 《Titanium and Cobalt Bimetallic Radical Redox Relay for the Isomerization of N-Bz Aziridines to Allylic Amides》.Computed Properties of C20H20BrP The article contains the following contents:
Herein, a bimetallic radical redox-relay strategy is employed to generate alkyl radicals under mild conditions with titanium(III) catalysis and terminated via hydrogen atom transfer with cobalt(II) catalysis to enact base-free isomerizations of N-Bz aziridines I [R1R3 = (CH2)3, R2 = H; R1R2 = CH2NTsCH2CH2, R3 = H; R1 = MeO2C(CH2)7, R2 = R3 = H; etc] to N-Bz allylic amides II. This reaction provides an alternative strategy for the synthesis of allylic amides from alkenes via a three-step sequence to accomplish a formal transpositional allylic amination. The experimental part of the paper was very detailed, including the reaction process of Ethyltriphenylphosphonium bromide(cas: 1530-32-1Computed Properties of C20H20BrP)
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.Computed Properties of C20H20BrP
