Fischer Carbene Complexes in Organic Synthesis: Metal-Assisted and Metal-Templated Reactions
Karl Heinz Dötz,Joachim Stendel +1 more
TL;DR: This review concentrates on group 6 metal carbene complexes with a special focus on chromium complexes since, because of their balance of reactivity and stability combined with easy accessibility, they are the most prominent members of the Fischer carbenes and have found the broadest application.

Fischer Carbene Complexes as Chemical Multitalents: The Incredible Range of Products from Carbenepentacarbonylmetal alpha,beta-Unsaturated Complexes.
TL;DR: Beyond doubt, the methodological arsenal of preparative organic chemistry cannot be imagined any more without the valuable transformations of the Fischer carbene complexes; it only remains to be seen whether one or other of the numerous new types of cocyclization products of these complexes can establish itself as a lead structure in the search for biologically active compounds.

Group 6 Fischer carbene complexes: “chemical multitalents” for multi-component reactions
TL;DR: The ability of heteroatom stabilized Fischer carbene complexes (FCCs) to participate in multicomponent reactions, which has allowed the construction of a large variety of highly functionalized structures through several patterns of reactivity, will be disclosed along the following lines.

(1-Alkynyl)carbene Complexes (= 1-Metalla-1-buten-3-ynes): Tools for Synthesis
Rudolf Aumann,Hubert Nienaber +1 more
TL;DR: In this article, the reactivity of (1-alkyny1) carbene complexes is discussed, especially if a regio-and/or stereoselective formation of C,C- or C,X bonds is achieved that might be utilized in organic synthesis.
