摘要:A convenient two-stage method has been developed for preparing benz[ d ]isothiazol-3(2 H )-ones from 2-bromobenzamides and sulfur in a one-pot process under copper catalysis conditions. The method is suitable for the synthesis of N -aryl-, benzyl-, and alkyl-substituted benzisoth...

摘要:An effective and accessible method was developed for the preparation of N -methylcarbazoles from N -(2-iodoaryl)- N -methylanilines. Cyclization occurred in the presence of potassium tert -butoxide and iron(II) bromide by a mechanism of radical homolytic substitution. Two regiois...
