Wang, Tao published the artcileA 3,4-dimercapto-3-cyclobutene-1,2-dione-chelated ruthenium carbene catalyst for Z-stereoretentive/stereoselective olefin metathesis, Related Products of esters-buliding-blocks, the main research area is dimercaptocyclobutenedione chelated ruthenium carbene catalyst preparation; olefin diastereoselective preparation; butenediol alkene cross metathesis ruthenium catalyst; alkene homometathesis ruthenium catalyst.
A ruthenium carbene catalyst chelated with a 3,4-dioxocyclobut-1-ene-1,2-dithiolate ligand was synthesized and its mol. structure was determined by single-crystal x-ray diffraction. The Ru catalyst had excellent catalytic activity with high yields and good Z/E ratios for the ring-opening metathesis polymerization (ROMP) of norbornene and for ring-opening cross metathesis (ROCM) reactions of norbornene/5-norbornene-2-exo, 3-exo-dimethanol with styrenes. The catalyst also had high Z-stereoretentivity (91:9-98:2) for cross-metathesis (CM) reactions of terminal olefins with (Z)-2-butene-1,4-diol. Like other Ru carbene complexes, the catalyst tolerates many different functional groups. The presented data, supported by DFT calculations, showed that the catalyst, bearing a chelating 3,4-dioxocyclobut-1-ene-1,2-dithiolate ligand, exhibited higher stability towards air than Hoveyda’s stereoretentive complex systems.
