Molecular Iodine Catalyzed Highly Rapid Synthesis of 1,5‐Benzodiazepine Derivatives Under Mild Conditions

Abstract Rapid reaction of o‐phenylenediamines with both cyclic and acyclic ketones in the presence of catalytic amount of iodine afforded 1,5‐benzodiazepine derivatives in excellent yields at room temperature.

Hexamethylenetetraamine-Bromine Catalyzed Rapid and Efficient Synthesis of Bis(indolyl)methanes

Summary.Highly rapid and convenient syntheses of bis(indolyl)methanes in excellent yields were carried out using the inexpensive and easily available catalyst, hexamethylenetetraamine-bromine (HMTAB). Mild reaction conditions, short reaction times, and excellent yields are important features of this method.

Cyanuric Chloride : an Efficient Catalyst for Ring Opening of Epoxides with Thiols Under Solvent-Free Conditions

2,4,6-Trichloro-1,3,5-triazine-catalyzed convenient and efficient ring opening of epoxides with thiols under solvent-free conditions is described. Short reaction time, mild reaction conditions, inexpensive and readily available catalyst, and excellent yields of products are attractive features of this methodology.
