title: Evidence for formation of silenes strongly influenced by reversed Si[double bond]C bond polarity.
abstract: [reaction: see text] Transient silenes that are strongly influenced by reversed Si[double bond]C bond polarization are formed upon heating of tris(trimethylsilyl)silylamides. The silenes are trapped with 2,3-dimethyl-1,3-butadiene to quantitatively yield only one of the possible diastereomers of the functionalized cyclic allylsilanes.
