Xu, Yuqin published the artcileThe Chan-Evans-Lam N-arylation of phosphonic/phosphinic amides, Synthetic Route of 197958-29-5, the publication is Tetrahedron (2017), 73(31), 4602-4609, database is CAplus.
A stoichiometric copper(II)-mediated arylation protocol of phosphinamides and phosphonamides was herein demonstrated. Various unreported N-aryl phosphinamides and phosphonamides were successfully prepared through Chan-Evans-Lam reaction with high efficiency (up to 88% yields) and good functional groups tolerance (30 examples) in the absence of any ligands or co-catalysts.
Tetrahedron published new progress about 197958-29-5. 197958-29-5 belongs to pyridine-derivatives, auxiliary class Pyridine,Boronic acid and ester, name is 2-Pyridinylboronic acid, and the molecular formula is C13H26N2, Synthetic Route of 197958-29-5.
