General description

2-(Trimethylsilyl)-1,3-dithiane participates in Lewis base-catalyzed 1,3-dithiane addition to electrophiles such as carbonyl compounds and N-substituted aldimines[1]. 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[2]. It is a versatile acyl anion equivalent[3][4].
