Selectivity in the electrochemical deprotection of cinnamyl groups from oxygen and nitrogen functionalities: carbonates versus carbamates
摘要:
Several cinnamyloxy carbamates and carbonates were subjected to electrochemical reduction, and the reductive fate of the cinnamyl group was investigated. Complete selectivity was observed in the removal of the cinnamyl group from oxygen versus nitrogen. (c) 2005 Elsevier Ltd. All rights reserved.

It's a benzyl kind of magic: In the title reaction proceeding with benzyl chloride as the oxidant, the benzyl group serves as a carbon ligand, thus having an η3‐coordination effect on palladium (see scheme). A variety of aldehydes and alcohols were selectively converted into the corresponding esters in good to excellent yields.
