Abstract

Paramagnetic complexes (η5-C5Me5)Ru(µ2-SPri)3Ru(η5-C5Me5)1 and (η5-C5Me5)Ru(µ2-SPri)2Ru(η5-C5Me5)2 react with HC[triple bond, length half m-dash]CSiMe3 to give a novel diamagnetic diruthenium complex (η5-C5Me5)Ru(µ2-H)(µ2-SPri)[η2-µ2-Me3SiC[triple bond, length half m-dash]CC([double bond, length half m-dash]CSiMe3)C[triple bond, length half m-dash]CSiMe3]Ru(η5-C5Me5)3 which easily releases a free alkyne trimer (Me3SiC[triple bond, length half m-dash]C)2C[double bond, length half m-dash]CHSiMe3 by air oxidation, whereas treatment of 1 with HC[double bond, length half m-dash]CTol affords another diamagnetic diruthenium complex (η5-C5Me5)Ru(C[triple bond, length half m-dash]CTol)(µ2-SPri)2Ru(C[triple bond, length half m-dash]CTol)(η5-C5Me5)6, (Tol =p-tolyl).
