1,1-Difluoro-2-triphenylsiloxybuta-1,3-diene as a potentially useful fluorine-containing building block: preparation and [4 + 2] and [2 + 2] cycloadditions
Abstract
1,1-Difluoro-2-triphenylsiloxybuta-1,3-diene has been conveniently prepared and undergoes [4 + 2] or [2 + 2] cycloadditions with various olefins.
