Abstract

Ruthenium olefin metathesis is without doubt one of the most thriving fields in modern synthetic chemistry. Applications in industry and recent developments in basic research make the study of alkylidene ruthenium compounds both exciting and rewarding. As usually recurrent in organometallic catalysis, the development of novel ligands, in particular alkylidene ligands, has had a pivotal role in the tremendous success of the area. This microreview details the evolution of the alkylidene ruthenium compounds, including simple alkylidenes, benzylidenes, Fischer carbenes, vinylidenes, allenylidenes, indenylidenes and the important sub-class of chelated alkylidenes, and includes a discussion of the significant effects these ligands have had on the precatalysts properties.(© Wiley-VCH Verlag GmbH & Co.
