摘要:A novel synthesis reaction for highly stereospecific tri- and tetra-substituted olefins is described. A single stereoisomer of stable α-halo-α,β-ester is produced in high yield by the reaction of aldehyde or ketone with a trihalogenated compound such as trichloroacetate in the presence of CrCl 2 in a solvent. By varying the amount of CrCl 2 used, the stable dihalohydrin intermediate may be obtained as well.
