An operationally simple, and cost efficient conversion of carboxylic acids into hydroxamicacid derivatives via a high‐energy mechanochemical activation is presented. This ball milling methodology was applied to a wide variety of carboxylic acids dramatically improving purification issues associated with this class of molecules, which still remain one of the main bottlenecks of classical methodologies

A viable nitrogen source for the aminohydroxylation reaction of terminal alkenes: By adding a N‐O based reoxidant onto an amino acid acyl carbon atom, compounds were obtained that facilitated catalytic turnover and also promoted the conjugation of an amino acid with an alkene. High levels of regioselectivity were observed, as well as good stereoselectivity induced by catalytic amounts of a chiral ligand

Dioxazolones and phosphines have been used to access N-acyl iminophosphoranes in copper(I) catalysis under simple thermal conditions. The synthetic utility of this protocol is demonstrated by a broad range of substrates with an excellent atom-economy. The optimization process showed that copper demonstrated as catalytic amount toward the targeted transformation. Functionalization studies of N-acyl
