Abstract
The skeletal reorganization of 1,6-enynes into 1-vinylcyclopentenes was cat alyzed by a cationic platinum complex under extremely mild conditions. The unusual rearrangement of the carbon skeleton, involving the cleavage of bot h the double and triple carbon-carbon bonds, was observed in certain cases and confirmed by C-13- and H-2-labeling experiments. Reaction mechanisms de scribing the rearrangement of carbocations are proposed.
