Descrição geral
2-(Trimethylsilyl)-1,3-dithiane participates in Lewis base-catalyzed 1,3-dithiane addition to electrophiles such as carbonyl compounds and N-substituted aldimines. It undergoes novel diazo transfer reaction with tosyl azide in hexamethylphosphoramide-THF to yield 2-diazo-1,3-dithiane, which on decomposition yields formal carbene adducts. It is a versatile acyl anion equivalent.

Lewis base-catalyzed 1,3-dithiane addition to electrophiles such as carbonyl compounds and N-substituted aldimines with 2-trimethylsilyl-1,3-dithiane (TMS-dithiane) is described. By the activation of the carbon-silicon bond in the presence of a Lewis base catalyst such as tetrabutylammonium phenoxide (PhONnBu(4)), a 1,3-dithiane
