Abstract
The solid state photoreactions of mixed crystals of acetylcoumarins and indole were investigated, and the mixed crystals were characterized by solid UV spectra, solid FL spectra and X-ray powder diffraction analysis. The photoreactions of 3-acetylcoumarin and its 7-acetyloxy, 7-benzoyloxy, 6-bromo and 5,6-benzo derivatives with indole in the solid state afforded condensation products 1-5, respectivelly, while 3-acetyl-6-nitrocoummarin with indole gave ring cleavage decarbonyl addition product 6. The products were identified by IR, 1H NMR, MS and elemental analyses.
