class of carbenes. The present study reveals that [(COD)IrCl]2 is found to be an efficient catalyst for the A/A class of carbenes, and Pd2(dba)3 for the D/A class of carbenes, for insertion into N–H bonds in water under mild reaction conditions. A reactivity comparison study with different classes of carbenes revealed that silver based catalysts are the right choice for the D/D class of carbenes for insertion

A novel approach for synthesizing α-amino acids <i>via</i> formate mediated hydrogen transfer using a carbon source
have developed a novel and practicalmethod for the preparation of α-amino acid derivatives under mild conditions. In this approach, the photoexcited naphthalene thiolate acts simultaneously as a photoexcited single-electron reductant and a hydrogen atom transfer (HAT) catalyst, enabling efficient metal-free radical–radical cross-coupling of formate with ketimines and aldimines.
