(equation presented) The anodic oxidation of {[[2-(2,2-dibutyl-2-stannahexyl)phenyl]methyl]thio}benzenes gave o-quinodimethanes which were trapped in situ by dienophiles to give the corresponding cycloadducts in excellent yields. The electron transfer and succeeding 1,4-elimination reaction was efficiently completed in a solution of lithium perchlorate/nitromethane in the presence of acetic acid. The reaction progress was quantitatively controlled by the passage of charge. By using this new method, an aryltetralin lignan skeleton was also synthesized.

Phenyl-, methoxy-, and acetoxy-substituted o-quinodimethanes (o-QDM) have been added to dimethyl fumarate and maleate to determine the stereoselectivity of the addition reaction.The o-QDM's were generated from the corresponding 1,3-dihydrobenzothiophen
