Phosphoranimide-metal catalysts and their role in C—O bond hydrogenolysis and hydrodeoxygenation (HDO) are disclosed. The catalysts comprise of first row transition metals such as nickel, cobalt and iron. The catalysts have a metal to anionic phosphoranimide ratio of 1:1 and catalyze C—O bond hydrogenolyses of a range of oxygen-containing organic compounds under lower temperature and pressure conditions than those commonly used in industrial hydrodeoxygenation.
This manuscript describes the synthesis of γ-lactam from the nitrogen insertion reaction of cyclobutanones using an oxime as an aminating reagent with a catalytic amount of Brønstedacid. This method was employed with a more stable oxime reagent, which is a precursor analog of hydroxylamine derivatives with explosive properties. The reaction was tolerated by various substituted cyclobutanones and less

synthesizing distal aminoacidderivatives by the ring-opening reaction of cyclic ketones, following the amino esterification functionalization of both terminals. To achieve this goal, we performed the ring-opening reaction of cyclic ketones with an aminating reagent and alcohol under metal- and photocatalysis-free conditions in a single step. The method directly afforded distal aminoacidderivatives bearing
