Conversion of Alcohols to Thiols via Tosylate Intermediates

Abstract

High yielding syntheses of mercapto terminated monodisperse dimer, trimer, and tetramer ethyleneoxide oligomers and of p-hydroxyphenethyl thiol via an alcohol-tosylate-thiol route are reported. Comparisons are made with the more conventional alcohol-bromide-thiol route.

Key Words

thiols - esters - alcohols - thiourea - ethyleneglycol oligomer
