Five-Coordinate Organo-Zirconocene-ate Complexes: Synthesis and Reactivity

Autor: Jean-Pierre Majoral, Yannick Miquel, Victorio Cadierno, A. Igau, Bruno Donnadieu

Publikováno v: Organometallics. 19:54-61

A variety of stable five-coordinate organo-zirconocene-ate complexes, 2-4, 9, 12a,b, 16, and 18, have been prepared and structurally characterized. The reaction process is based on both (i) the nucleophilic attack of tertiary phosphines on acetylenic

Publikováno v: Organometallics. 16:3086-3088

Diacetylenic phosphanes are cleanly transformed when reacted with zirconocene into zirconacyclopentadiene phosphiranes. These new cyclic systems are the source of a variety of unsaturated phosphorus compounds like phospharadialene or alkenyl alkynyl
