General description

tert-Butylsulfinyl chloride can be synthesized by using tert-butylmagnesium chloride as the starting material via a multi-step synthesis process.

Application

tert-butylsulfinyl chloride can react with primary and secondary amines to form tert-butylsulfinamides, which on oxidation forms base stable tert-butylsulfonamide. It can also react with 1-thiosugars to form the corresponding carbohydrate thionolactones.
