Abstract
Paramagnetic complexes (η5-C5Me5)Ru(µ2-SPri)3Ru(η5-C5Me5)1 and (η5-C5Me5)Ru(µ2-SPri)2Ru(η5-C5Me5)2 react with HCCSiMe3 to give a novel diamagnetic diruthenium complex (η5-C5Me5)Ru(µ2-H)(µ2-SPri)[η2-µ2-Me3SiCCC(CSiMe3)CCSiMe3]Ru(η5-C5Me5)3 which easily releases a free alkyne trimer (Me3SiCC)2CCHSiMe3 by air oxidation, whereas treatment of 1 with HCCTol affords another diamagnetic diruthenium complex (η5-C5Me5)Ru(CCTol)(µ2-SPri)2Ru(CCTol)(η5-C5Me5)6, (Tol =p-tolyl).Keywords
