Abstract
In order to investigate the generality of this reaction, we have prepared several silanes having one cinnamyloxy ligand and various alkenyloxy groups attached to the silicon (Scheme 1). Compounds 2a-h were irradiated and desilylated, and the photoproducts were separated by chromatography. In general, isomerization about the cinnamyl double bond occurs in the absence of cycloaddition. Both the allyl (2a) and crotyl (2b) irradiations ...
