In situ generation of n-butanethiol and its reaction with electron-deficient olefines

Gariani, Rogerio A.,Santos, Alcindo A. Dos,Comasseto, Joao V.

, p. 789 - 795 (2008)

n-Butanethiol is generated in situ by sequential addition of n-butyllithium and water to elemental sulfur. The n-butanethiol formed was reacted with electron-deficient olefines to give Michael-type addition products in good yields. The method avoids the manipulation of the bad-smelling n-butanethiol.
