3‐Methyl‐4,6‐diphenylfuro[3,4‐<i>d</i>]isoxazol – Ein neues heterocyclisches System

Abstract

3‐Methyl‐4,6‐diphenylfuro[3,4‐ d ]isoxazole – A New Heterocyclic System Metal‐catalyzed nitrogen extrusion from the diazo compound 8 yields 3‐methyl‐ 4 ,6‐diphenylfuro[3,4‐ d ]isoxazole ( 9 ). Compound 9 has been investigated by luminescence spectroscopy. Ab initio and/or semiempirical (PM3) quantum‐chemical calculations on the parent compounds 1a , 2a , 3a , b , the phenylsubstituted derivatives 1b , 2b , 9 , and on 4 in ground and excited states are performed.
