Abstract
Hydrozirconation using chlorobis (η-cyclopentadienyl) hydridozirconium (IV) (1) has recently been developed as a procedure for functionalizing alkenes, alkynes, and 1, 3-dienes via organozirconium (IV) intermediates. These intermediates react with a variety of electrophilic reagents to give organic products in high yield. Via transmetalation the zirconium intermediates also serve as, precursors of reactive organometallic complexes of metallic elements whose chemistry is well established with regard to C-C bond formation processes. Synthetic and mechanistic aspects of organozirconium chemistry are discussed.
