✦ Synopsis

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 earbenes 2 with triphenyl phosphine resin 1. The supported alkoxyearbene 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 aminoaeids with alkoxycarbene 2a.
