摘要：

A series of polymer-bound Fischer chromium alkoxy and amino carbene type I complexes were synthesized by the thermal exchange of a CO ligand in chromium pentacarbonyl carbenes 2 with triphenyl phosphine resin 1. The supported alkoxycarbene 3a proved to be reactive towards primary amines, and afforded the polymer-bound aminocarbenes 5. Type II aminocarbenes were also prepared by reacting polymer-supported aminoacids with alkoxycarbene 2a. (C) 1999 Elsevier Science Ltd. All rights reserved.
