Organotransition metal alkyls and aryls are organometallic compounds in which an alkyl or aryl group is directly bonded to a transition-metal atom through a metal–carbon σ bond. They are important intermediates in catalytic reactions such as polymerization, hydrogenation, cross-coupling and olefin transformations. Depending upon the nature of the organic group, the number of metal–carbon bonds, and the arrangement of the ligands around the metal, organotransition metal alkyls and aryls can be classified into several types. 1. Simple alkyl and aryl complexes These compounds contain one or more alkyl or aryl groups directly attached to the transition metal by σ bonds. They are represented generally as (M-R), where (R) is an alkyl group, or (M-Ar), where (Ar) is an aryl group.
