文摘

The Ru dithiolate alkylidene species (SIMes)Ru(CHPh)(O(CH₂CH₂S)₂) (1) reacts with 1 and 2 equiv of BCl₃ to give (SIMes)RuCl(CHPh)(Cl₂B(SCH₂CH₂)₂O) (2) and [(SIMes)Ru(CHPh)(Cl₂B(SCH₂CH₂)₂O)][BCl₄] (3), respectively. Compounds 1 and 2 are inactive in ROMP, RCM, and CM reactions, whereas 3 is an active catalyst for these metatheses.
