Halide-Free Dehydrative Allylation Using Allylic Alcohols Promoted by a Palladium—Triphenyl Phosphite Catalyst.

The triphenyl phosphite-palladium complex was found to effect catalytic substitution reactions of allylic alcohols via a direct C-O bond cleavage. The dehydrative etherification proceeded efficiently without any cocatalysts and bases to give allylic ethers in good to excellent yields.
