Mechanism insights into an unexpected isomerisation reaction observed during conversion of N-benzyl piperazinones to corresponding N-benzyl thio-piperazinones
摘要:
An interesting and surprising rearrangement was observed during the reaction of 4-N-benzyl piperazinone derivatives with Lawesson's reagent as a thionating agent. Investigation into the possible mechanism responsible for these results is reported herein. (c) 2010 Elsevier Ltd. All rights reserved.
