Abstract
The photochemical behaviour of several derivatives of 2-amino-2-phenylindan-1,3-dione, substituted in the amino group was investigated by means of steady state irradiation and flash photolysis. It is shown, that two photoisomerization reactions take place simultaneously: i) photoisomerization to 3-aminosubstituted-benzylidene-phthalides; ii) photoisomerization to 2-substituted-3-phenylisoquinolinones.Both processes result from a bond rupture according to a Norrish type I reaction mechanism.Keywords
