Simple synthesis of new 2-imino-4-amino-1,3-dithioles and 2-lmino-4-hydroxy-1,3-dithioles
Abstract
A selective reaction of various triethylammonium dithiocarbamates salts with α-α-dicyano epoxides and α-cyano-α-carbethoxy epoxides leads to new 2-Imino-4-hydroxy-l,3-dithioles or to new 2-Imino-4-amino-1,3-dithioles depending on the experimental conditions. The NLO properties of these dithioles are presented.
