✦ Synopsis

2-methyl-2-cyclopentene-l-ones are produced by treating l-vinyl-1-cyclobutanols with bis(benzonitrile)palladium dichloride and benzoquinone in THF. The vinylcyclobutane rearrangement is a cyclohexannulation which needs an olefin as the ultimate starting material. Danheiser,' Cohen,3'4 and others4 have studied the rearrangement
