Synthesis and Characterization of a New Bimetallic Catalyst, GJL-46, and Its Use in the Catalytic Hydrosilylation of Phenylacetylene.

Abstract

A new bimetallic catalyst was synthesized from the metalation of 1,1'-(1,3-phenylene) bis(4-butyl-1 H-1,2,4-triazol-4-ium) iodide with silver oxide and the transmetalation of that complex with Rh(COD)2OTf. The structure of the compound, GJL-46, with molecular formula C34H46I2N6Rh2, was confirmed with mass spectra analysis, 1H NMR and 13C NMR. The catalytic activity of the produced molecule, GJL-46, with molecular formula C34H46I2N6Rh2, in the hydrosilylation of phenylacetylene is reported
