Abstract

In contrast to the well documented rearrangement of silyl- carbenes to sila-alkenes,l the rearrangement of silanediyls to sila-alkenes is quite rare. To our knowledge, the photo- chemically or thermally induced isomerization of dimethyl- silanediyl to 2-silapropene is the only known example of a silanediyl to sila-alkene conversion.2 Since the intramolecular rearrangement of cycl opropyl- carbenes to cyclobutenes is a well known reaction of carbene~,~ we have ...
