Functional sulfur-containing compounds 2. Synthesis of 3-chloropropyl and 4-chlorobutyl alkyl (phenyl) sulfones by the oxidative chlorination of 3-hydroxypropyl and 4-hydroxybutyl alkyl(phenyl) sulfides and sulfoxides
A general, efficient, and experimentally simple method for the generation of sulfenate salts has been developed using β-sulfinylesters as substrates. The process is based on a retro-Michael reaction, initiated by deprotonation at low temperature. Upon treatment with alkyl halides, the liberated sulfenates are subsequently converted into sulfoxides in good to excellent yield. Extension of the methodology

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.

Alkanethiols, selenols and tellurols are generated in situ by reaction of elemental sulfur, selenium and tellurium with commercial alkyllithiums, followed by reaction with deoxygenated water. The alkanechalcogenols react in situ with activated ole. ns in a Michael- type addition reaction. (c) 2008 Elsevier B. V. All rights reserved.
