I. Nakamura et al., PALLADIUM-CATALYZED ALKYLATIVE DIMERIZATION BETWEEN PRONUCLEOPHILES AND VINYLTINS, Chemical communications, (16), 1997, pp. 1583-1584
In the presence of catalytic amounts of Pd-2(dba)(3).CHCl3 and dppb, t
he reaction of pronucleophiles 1 with vinyltins 2 gives the correspond
ing alkylative dimerization products of the vinyl group, 1,4-disubstit
uted butene derivatives 3, in good to high yields.
