Abstract

The unstable species [(C₅H₅)Ru(PPh₃)₂(η ¹,S-C₄H₄S)]⁺ has been observed in solution and shown to convert to [Ru(C₅H₅)(η⁵-C₄H ₄S)]⁺. An η¹,S-thiophene complex has been stabilized in the form [(C₅H₄CH₂C₄H ₃S)Ru(PPh₃)₂]X (2). An X-ray structural study of 2 (X = BPh₄) confirms the structure and shows that the sulfur is pyramidal. Displacement reactions of 2 have been studied.
