Electronic Structure and Reactivity of Metal Carbenes,on of .-heterocyclic carbene complexes this classification needs to be extended because of the very different electronic character of these ligands. The electronic structure of these different kinds of carbene complexes is analysed and compared to analogous silylenes and germylenes. The relationship

Cycloaddition Reactions of Group 6 Fischer Carbene Complexes,ocycles) not readily accessible through conventional methods. In this chapter, a summary of cycloaddition reactions involving group 6 Fischer carbene complexes is presented. Firstly, two-component coupling reactions where a substrate reacts with the carbene complex to afford three- to nine-membered

Chromium-Templated Benzannulation Reactions,w, topical aspects of this reaction concerning its mechanism and the chemo-, regio- and stereoselectivity are summerised and discussed in detail. Special attention is paid to the asymmetric benzannulation reaction and, finally, the importance of this reaction as a key step in the total synthesis of

Photoinduced Reactions of Metal Carbenes in Organic Synthesis,plete listing of published examples. A majority of these processes involve CO insertion to produce species that have ketene-like reactivity. Cycloaddition reactions presented include reaction with imines to form β-lactams, with alkenes to form cyclobutanones, with aldehydes to form β-lactones, and w
