摘要：

(Chemical Equation Presented) ... or a touch of gold: Electrocyclization of the pentadienyl cation produced on coordination of cationic phosphinegold(I) to vinyl allenes results in the regioselective formation of highly functionalized cyclopentadienes. The regioselectivity of the reaction is consistent with an intramolecular 1,2-hydrogen shift of a gold(I)-carbenoid intermediate (see scheme). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
