A facile direct deposition approach for the preparation of recyclable Pd/C catalysts simply by stirring a solution of tris(dibenzylideneacetone)dipalladium(0) with a suitable carbon material was evaluated. An extraordinarily rapid catalyst preparation procedure (<5 min) under mild conditions and its excellent performance in cross‐coupling and hydrogenation reactions were demonstrated. The key point for catalyst design is the direct deposition of Pd0 centers onto the highly accessible surface area and the avoidance of ill‐defined PdII/Pd0 states.

A highly‐efficient catalytic system for hydrodebenzylation reaction is described. The cleavage of O‐benzyl and N‐benzyl protecting groups was performed using an uncommonly low palladium loading (0.02–0.3 mol%; TON up to 5000) in a relatively short reaction time. The approach was used for a variety of substrates including pharmaceutically important precursors, and gram‐scale deprotection reaction was shown. Transfer conditions together with easy‐to‐make Pd/C catalyst are the key features of this debenzylation scheme.magnified image
