A FACILE METHOD FOR THE PREPARATION OF FUNCTIONALIZED 2,3-DISUBSTITUTED-1,3-BUTADIENES
Zhu, Lishan,Rieke, Reuben D.
, p. 2865 - 2866 (1991)
Functionalized 2,3-disubstituted-1,3-butadienes were readily prepared by reacting functionalized organozinc compounds with 1,4-dichloro-2-butyne or 1,4-ditosyloxy-2-butyne mediated by Cu(I) salts.
