噻唑烷类手性配体在不对称硅氢化反应中的应用(Ⅱ)*
催化学报,1997,18(4):341~344,-0001,():
Four 1,3-thiazolidine chiralligands with various aromatic substituents were synthesized by condensation of L-cysteine or its ester with aldehyde or ke-tone.The catalysts prepared by the reaction of these ligands with I Rh(COD)-Cl]2 were used to catalyze the asymmetric hydrosilylation of acetophenone.TWO high reactive and selective chiral ligands with pyridyl were sifted.The chemical yield of the catalytic reaction is up to 90%,the optical yield could reach about 80%(e.e).The coordination structure of the catalysts was discussed.
