Improved catalytic process for the synthesis of functionalized dibenzo 1,3 diazepines using metal nanoparticle based catalysts

摘要

The present invention provides an improved catalytic process for the synthesis of dibenzo[1,3]diazepines by coupling of amines with aldehydes in the presence of metal nanoparticles as catalyst. The process has certain advantages as this method involves a single step preparation, fast reaction rate, clean reaction with high product yield and also the method has advantage of reusability of the catalytic system.
