No electron-withdrawing or electron-releasing substituents are necessary for the substrates in the rhodium-catalyzed [4+2] cycloaddition reaction between a vinylallene and an ordinary alkyne under mild conditions [Eq. (1)]. The use of the strongly electron-accepting P[OCH(CF ) ] ligand affords the o

Directed Intermolecular (4 + 2) Cycloaddition of Unactivated 1,3-Diene Substrates with High Regio-and Stereoselectivities. -Pd(0)-catalyzed cycloaddition of vinylallenes with ordinary 1,3-dienes leads to cyclohexene derivatives. High regio-and stereoselectivities are achieved under mild conditions
