Photolysis of azidocinnamates: isolation of azirine trimers; X-ray crystal structure of triethyl 2,4,9-tri-o-tolyl-1,3,8-triazatricyclo-[4.3.0.03,5]non-7-ene-5,6,7-tricarboxylate
Abstract
Photolysis of the azidocinnamates (1) gives trimers of the azirines (2); X-ray crystallographic analysis establishes the triazatricyclononene structure (6) for these trimers.
