✦ Synopsis

The addition of [Ph 2 C=NCHCO 2 Me] ± to [(C 6 H 7 )Fe(CO) 3 ] + , [(C 7 H 9 )Fe(CO) 3 ] + , [(C 7 H 7 )M(CO) 3 ] + (M = Cr, Mo) and [(C 2 H 4 )Re(CO) 5 ] + gives derivatives of aamino acids with organometallic side chains. The structure of [(g 4 -C 6 H 7 )CH(N=CPh 2 )CO 2 Me]Fe(CO) 3 was determined by X-ray diffraction. From the adduct of [Ph 2 C=NCHCO 2 Me] ± and [(C 7 H 7 )Mo(CO) 3 ] + the Schiff base of a new unnatural aamino acid, Ph 2 C=NCH(C 7 H 7 )CO 2 Me, was obtained.
