摘要

Reactions of ruthenium indenylidene starting material [Ru(PPh₃)₂(Ind)Cl₂] (Ind = 3-phenylinden-1-ylidene) with potassium dichalcogenoimidodiphosphinates K[R₂P(E)NP(E鈥?R₂] afforded a series of complexes [Ru(PPh₃)(Ind){泻E,泻E鈥?R₂P(E)NP(E鈥?R₂}Cl] [R = Ph, E = E鈥?#xA0;= S (1a); R = Ph, E = E鈥?#xA0;= Se (1b); R = ⁱPr, E = E鈥?#xA0;= S (1c); R = ⁱPr, E = E鈥?#xA0;= Se (1d); R = Ph, E = S, E鈥?#xA0;= Se (1e); R = ⁱPr, E = S, E鈥?#xA0;= Se (1f)] which were characterized by microanalyses, IR and NMR spectroscopies. The molecular structure of 1a has been confirmed by single-crystal X-ray diffraction. The catalytic reactivity of the ruthenium indenylidene complexes in the ring closing metathesis of diethyl 1,2-diallylmalonate has also been investigated.
