Palladium complexes with phosphinooxazoline ligands are very efficient cata
lysts for the coupling of alkynes to enynes. The catalyst system could be e
mployed in solvent-free reactions and provided an efficient means for the r
egiocontrol of cross-coupling reactions between mono- and disubstituted alk
ynes. Using enantiomerically pure ligands, kinetic resolution of racemic pr
opargylic alcohols to optically active enynes was achieved.
