X-RAY CRYSTAL STRUCTURE OF DIBENZO[a,d]CYCL[2.2.3)AZINES

摘要

The results of X-ray analyses of a novel type of heterocycles,2-benzoyl- and 1,3-dimethyldibenzo[a,d]cycl[2.2.3]azines were described,which offer further evidence for the 18PI peripheral conjugate nature of dibenzo-[a,d]cycl[2.2.3]azines.The molecules are essentially planer as is the parent cycl[2.2.3]azine,but less strained.
