Nickel complexes are found to be catalytically active in the cross-coupling reactions of allenic bromides with alkyl metals to give substituted allenes in excellent yields. The catalytic process proceeds generally with inversion of configuration in the allenyl moiety.

A stereoselective route to alkenyl sulfi
A stereoselective route to alkenyl sulfides through the palladium-catalyzed cross-coupling reaction of 9-alkyl-BBN with 1-bromo-1-phenylthioethene or (E)- and (Z)-2-bromo-1-phenylthio-1-alkenes

The reaction of 9-alkyl-9-BBNs with 1-bromo-i-phenylthioethene or (E)-and (Z)-2-bromo-lphenylthio-1-alkenes takes place readily in the presence of Pd(PPh& and sodium hydroxide to afford stereodefmed vinylic sulfides in excellent yields.
