Chapter Five - Organometallic Intermediates of Gold Catalysis

Abstract

This review summarizes the isolated organometallic compounds which represent analogues of intermediates of homogeneous gold-catalyzed organic reactions or authentic intermediates isolated under specific reaction conditions preventing a full turnover of the catalytic cycle. This covers π-complexes of gold with coordinated alkenes, arenes, allenes, and alkynes. But also subsequent intermediates of typical catalytic cycles like vinylgold complexes, alkylgold complexes, and gold hydrides. The geminal diaurated complexes, which in the context of dual gold catalysis became an important topic again, and gold carbenoids represent another subject. Both the oxidation states gold(I) and gold(III) are included.
