Beschreibung

Allgemeine Beschreibung

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.
