Abstract
2-Benzylidene-4-aza-1,3-indanediones have been synthesized and their structures have been investigated by NMR spectroscopy and quantum chemistry in the AM1 approximation. It was established that rotation about the exocyclic C(2)=C(10) formal double bond occurs in chloroform solutions of these compounds. The energy characteristics of this process have been determined experimentally and estimated theoretically.
