Formation of dinuclear ruthenacyclopentenyl complexes from reactions of Cp*Ru(μ-SPri)2RuCp* (Cp* = η5-C5Me5) with terminal alkynes and subsequent ring-opening reaction induced by ButNC to give diruthenium μ-alkenyl complexes

Coordinatively unsaturated complex Cp*Ru(μ-SPri)2RuCp* (1, Cp* = η5-C5Me5) reacts with excess HC≡CR (R = Tol, C=CH(CH2)3CH2; Tol = 4-C6H4Me) to form dinuclear ruthenacyclopentenyl complexes Cp*Ru(μ-SPri)[η2:η 3-μ-CH(Tol)C{C(Tol)=CHSPri}CHC(Tol)]RuCp* (3) and CP*Ru(μ-SPri[η2:η 3-μ-C{C(C=CH(CH2)3CH2)=CHSPr i}CHC{(CH2)3CH2}CH]RuCp* (4). These dinuclear metallacycles 3 and 4 are readily converted to μ-σ,π-alkenyl complexes Cp*-(ButNC)Ru(μ-SPri)[η 1:η2-μ-C(Tol)=CHC{C(Tol)=CHSPr i}=CH(Tol)]RuCp*(5) and Cp*(But-NC)Ru(μ-SPri)[η 1:η2-μ-C{C(C=CH(CH2)3CH 2)=CHSPri}=CH{C=CH(CH2)3CH 2}]RuCp* (6), respectively, through ButNC-induced ring-opening reactions with retention of the singly bonded diruthenium core bridged by a thiolato ligand. The structures of 3-6 have been determined by X-ray crystallography.
