Synthesis and evaluation of Naphthalene-1, 8-dithiolate chelating ruthenium carbene catalyst for Z-Stereoretentive olefin metathesis

Abstract

A highly Z-stereoretentive olefin metathesis ruthenium carbene catalyst containing a naphthalene-1,8-dithiol ligand was synthesized, and the structure was determined by single-crystal X-ray diffraction. The new ruthenium carbene catalyst could catalyze cross-metathesis reactions of terminal alkenes with (Z)-but-2-ene-1,4-diol to give highly Z-stereoretentive products. Like to other ruthenium carbene catalysts, the new complex tolerates many different functional groups.
