Abstract: The prodn. of bridged half-sandwich complexes of formula (I) comprises reacting cyclopentadienides of formula (II) with aziridines (III) and then reacting the ligand systems obtd. (IV) with metallating agents and MXn+2. M = Sub-gp. IV or V metal or lanthanide; X = halo, H, 1-10C alkyl, 3-10C cycloalkyl, 6-15C aryl, 7-15C alkylaryl or -OR (with R = 1-10C alkyl, 6-15C aryl, or alkaryl, aralkyl, fluoroalkyl or fluoroaryl with 1-10C alkyl gps. and 6-20C aryl gps.). n = valency of M minus 2; R = H, 1-10C alkyl, 3-10C cycloalkyl (opt. substd. with 1-10C alkyl), 6-15C aryl, (6-20C aryl)-(1-10C alkyl) or -Si(R )3 (with R = 1-10C alkyl, 6-15C aryl or 3-10C cycloalkyl); R -R = as for R , opt. with two adjacent gps. forming a 4-15C cyclic gp.
