摘要：

The palladium catalyzed addition of methylmalononitrile 4a to arylallenes 3 affords the internal adducts 5 and 6 either predominantly or exclusively when an electron-withdrawing group is present at the para-position, whereas it gives the terminal adduct 7 exclusively when an electron-donating group is present at the para-position.
