C–H activation of a coordinated thiacyclophane: cyclometallation of 2,11-dithia[3.3]orthocyclophane by ruthenium(II)

Abstract

Reaction of (η⁶-benzene)ruthenium(II)tris(acetone) solvate with 2,11-dithia[3.3]orthocyclophane leads to coordination of the sulphur donors and deprotcnation of a methylene carbon to give the cyclometallated complex [(η⁶-C₆H₆)Ru(o-C₆H₄CHSCH₂-o-C₆H₄CH₂SCH₂)]⁺; an X-ray study shows that Cyclometallation occurs at one of two sites in the complex and leads to the formation of a strained three-membered C–Ru–S ring.
