3,3-Dimethylacylthioureas: "S", "-S", "U" or "W" conformation?

Mostrar todas las versiones(3)

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 acylthiour eas and the corresponding anions. The high regioselectivity towards S-alkylation is explained on the...
