(S)-(-)-5,5',6,6'-TETRAMETHYL-3,3'-DI-TERT-BUTYL-1,1'-BIPHENYL-2,2'-DIOL Usage And Synthesis

Reaction

The new Schrock-Hoveyda, chiral molybdenum catalyst can effect various modes of enantioselective olefin metathesis with excellent selectivity.

Uses

(S)-5,5′,6,6′-Tetramethyl-3,3′-di-tert-butyl-1,1′-biphenyl-2,2′-diol, a biphenyl chiral ligand is used to prepare mono- and bidentate phosphites applicable as catalysts in the hydroformylation of allyl cyanide, heterocyclic olefins, and asymmetric hydrogenation of dimethyl itaconate.

General Description
