Abstract
We report a study of 3,3-dimethyl substituted acylthioureas. X ray data and quantum mechanical calculations demonstrated that the "S" conformation is the most stable both for the acylthioureas and the corresponding anions. Th e high regioselectivity towards S-alkylation is explained on the basis of t he localization of the HOMO mainly over the sulfur atom.
