Functionalized allylsilanes 1-4 undergo palladium(II) catalyzed ring closur
e to afford 4- and/or 5-substituted 2-vinyltetrahydrofurans (5-8) under mil
d conditions. The catalytic reactions proceed through (eta(3)-allyl)palladi
um intermediates formed by palladadesilylation of the allylsilane substrate
