Preparation of polyfunctional diorganomercurials and their transmetallation to diorganozincs. Applications to the preparation of optically active secon

Two new methods of preparation of functionalized diorganomercurials have been developed. The first method involves a substitution reaction of (ICH2 Their transmetallation with zinc dust (toluene, 80[deg]C, 3-5 h) affords dialkylzincs which add enantioselectively to aldehydes in the presence of a caPeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29788/1/0000130.pd
