Palladium-catalyzed additions of silyl-element bonds to bicyclopropylidene-A new access to bicyclopropyl and functionally substituted cyclopropylidenepropane derivatives

Palladium-catalyzed additions of disilanes, silylboranes, silylstannanes, and silyl cyanides across the double bond of bicyclopropylidene proceed with remarkable ease by two modes yielding either bicyclopropyl or cyclopropylidenepropane derivatives.
