Mixed crystals, prepared by resolidification of the melt of a mixture of 5-formyl-1,3-dimethyluracil (1a) and antipyrine (7) crystals (molar ratio, 1:2.5), and irradiated with a high-pressure mercury lamp under nitrogen, gave a photocondensation prod

A number of fluorescent 3-arylcoumarins (3-aryl-2H-1-benzopyran-2-ones) have been synthesized by the photo-coupling of 3-bromocoumarin with aromatic and heteroaromatic compounds. The structure of 3-(1-naphthyl)coumarin was confirmed by X-ray crystall

Irradiation of the mixed crystals between 5-formyl-1,3-dimethyluracil ( 1 ) and indole ( 2 ) gave 5-(bis-1-indolyl)methyl-1,3-dimethyluracil ( 3 ), whereas 1,3-dimethyluracil was the sole product in the photolysis of 1 and 2 in solution.

Solid-state photodimerization of coumarin in the presence of a crystal lattice-controlling substance
Publikováno v:
Tetrahedron. 45:6979-6986
Coumarin, which is known to be photostable in the solid state, underwent photochemical dimerization when admixing a crystal lattice-controlling substance, such as antipyrine and phenanthrene to coumarin to form a mixed crystal. The IR, UV, fluorescen
