Abstract

Starting from com. available 3-methylindole and 1,3-diiminoisoindoline, the BF2 complex of indol-2-yl-isoindol-1-ylideneamine (I) was prepd. in three steps. Its wavelength of max. visible absorption is similar to that of a tetra-phenyl-conjugated azadipyrromethene BF2 complex (II). [on SciFinder(R)]
