Mono- and Bis-acetylidoruthenium(II) Complexes by Controlled Metathesis of Methylruthenium Complexes with Acetylenes
摘要:
Acetylido methyl ruthenium(II) complexes, trans-Ru(C CR)(CH3)(dmpe)(2), were synthesized in a single metathesis reaction from trans-Ru(CH3)2(dmpe)2 at ambient temperature; at elevated temperatures the reaction yields trans-Ru(C CR)(2)(dmpe)(2). Addition of a second terminal acetylene to a methanol solution of trans-Ru(C CR)(CH3)(dmpe)(2) results in the formation of trans-Ru(C CR)(C CR')(dmpe)(2).
