Tetrylidyne Coordination Modes: Vinyl-Type Germa-Ruthena Anion [Ru=Ge:] -and its Reaction with Monofluorobenzene

Abstract

Ruthenium germyl complex [(Ph3P)ClRuGeCl2(C6H3-2-{η 6 -Trip}-6-Trip)] (1) is reduced with four electrons to yield the vinyl anion type complex [(Ph3P)Ru=GeK(C6H3-2-{η 6 -Trip}-6-Trip)] (3a) exhibiting a novel coordination mode for a germylidyne ligand. Formation of a gold-germanium bond in reaction with [(Ph3P)AuCl] and reaction with monofluorobenzene is presented.
