S. Onozawa et al., PALLADIUM-CATALYZED BORYLSILYLATION OF ALKYNES AND BORYLSILYLATIVE CARBOCYCLIZATION OF DIYNES AND AN ENYNE COMPOUND, Chemical communications, (13), 1997, pp. 1229-1230
Addition reactions or addition-carbocyclization reactions of a borylsi
lane with alkynes, alpha,omega-diynks or an enyne compound proceed eff
iciently in the presence of palladium catalysts, P(OCH2)(3)CEt being t
he ligand of choice.
