Synthesis and Characterization of Substituted 2-Diazo-1-oxo-1,2-dihydronaphthalenes and Their Products of Photolysis and Thermolysis

Several 2-diazo-1-oxo-1,2-dihydronaphthalenes (1, 2) have been synthesized by reaction of selected hydroxy compounds and 2-diazo-1-oxo-1,2-dihydronaphthalene-5- and -4-sulfonylchloride, respectively.Photolysis as well as thermolysis of 1 and 2 leads to final products, the nature of which depends on the position of substitution.So, reactions of 5-substituted derivatives (1) yield the corresponding indene-3-carboxylic acids 3 and their esters 5, respectively.In contrast, reactions of 4-substituted derivatives (2) lead to the formation of the 1-sulfo-indene-3-carboxylic acid derivatives 4 and 6.Prepared compounds have been characterized by means of mass, ultraviolet, infrared, 1H-n.m.r. and 13C-n.m.r. spectroscopy.
