Abstract
Development of nucleophilic organometallic species plays an important role in organic synthesis, especially for construction of carbon skeletons. This account describes the following synthetic reactions with novel organometallic species: (1) Preparation of alkenylchromium reagents for chemoselective addition to aldehydes, (2) Generation of geminal dimetallic species of zinc and chromium for the Wittig-type olefination, (3) Preparation of tantalum-alkyne complexes and their synthetic use, (4) Activation and deactivation of zinc with a catalytic amount of lead, (5) Control of one-electron transfer and its application to sequential radical and anionic reactions, (6) Rhenium and manganese catalyzed-Barbier-type addition of aromatic compounds to aldehydes based on C-H bond activation. The account focuses on the background to the research and how the reactions were discovered.
