Notes:
Several 2-diazo-1-oxo-1,2-dihydronaphthalene{ (1, 2) have been synthesized by reaction of selected hydroxy compounds and 2-diazo-1-oxo-1,2-dihydzonaphthalene-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. ind 13C-n.m.r. {pectroscopy.
