On the control of the site of methylation of the cyanide complex [Mo2(η5-C5H5)2(CO)(CN)(µ-SR)2]– by the substituents of the thiolate bridges (R = Me, Pri, CF3)

Abstract

The substituents of the bridging sulfur atoms exert an electronic control on the site of methylation of the cyanide complex [Mo₂(η⁵-C₅H₅)₂(CO)(CN)(µ-SR)₂]^–: the methylation can be diverted from a sulfur Ione pair to the cyanide ligand on changing the electronic properties of the R groups from electron-releasing to electron-withdrawing, respectively.
