Photochromism of Simple 1,8a-Dihydroindolizines and 1,8a-Dihydro-5-azaindolizines

In this paper we report on the synthesis of new photochromic 1,8a-dihydroindolizines and 1,8a-dihydro-5-azaindolizines 19 and betaines 18 as well as their precursors 3,3-diphenyl-3H-pyrazoles 13 and cyclopropenes 15.The stuctures of the betaines 18 are proved for the first time by X-ray analysis of 18l.The last part of this paper deals with Hammett correlations of the rate constant of the 1,5-electrocyclisation and MINDO/3 calculations of the thermal ring closure 18 -> 19.
