Dithioacetal as a 1,1-zwitterion synthon. Synthesis of functionalized alkenes by the coupling of benzylic dithioacetals with another 1,1-zwitterion synthon

Reaction of a dithioacetal sequentially with BuLi and alkyl bromide having an electron withdrawing substituent at the α-position followed by treatment with neutral alumina gives the corresponding olefination product in moderate to good yields.

Reinvestigation on Thermal Cycloaddition of 1-Aryl-2-(9-fluorenylidene)-1-haloethylenes

The thermal treatment of 1-bromo-2-(9-fluorenylidene)-1-phenylethylene afforded three different types of cycloaddition products.The 1-tolyl homolog showed similar trends, but the chloro analog gave only two types.These results suggest that reactions
