Dithioacetals undergo desulphurisation–dimerisation to give the corresponding dimeric alkenes in good to excellent yields on treatment with W(CO)6.
二硫缩醛经过脱硫-二聚反应后,用W(CO)6处理可获得相应的二聚烯烃,收率好至极好。

Reductive McMurry-type dicarbonyl coupling of certain aryl and α,β-unsaturatedcarbonylcompounds to give alkenes can be accomplished using chlorotrimethylsilane and zinc by a novel mechanism which does not involve pinacolic coupling and diol deoxygenation.
