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 chromi
um pentacarbonyl carbenes 2 with triphenyl phosphine resin 1. The supported
alkoxycarbene 3a proved to be reactive towards primary amines, and afforde
d the polymer-bound aminocarbenes 5. Type II aminocarbenes were also prepar
ed by reacting polymer-supported aminoacids with alkoxycarbene 2a. (C) 1999
