Abstract

A synthetic approach to a benzoselenete derivative is examined. Photolysis of 2-diazobenzo [b] selenophen-3 (2H)-one (7) in methanol gave mainly 2-methoxybenzo [b] selenophen-3 (2H)-one (1 1). Photolysis of 3-diazobenzo [b] selenophen-2 (3H)-one (8) in methanol gave dimethyl 1, 5-diazo [b,~ diselenocin-2, 6-dicarboxylate (14) instead of methyl 2H-1- benzoselenete-2-carboxylate (9). 14 is generated presumably by dimerization of the ...
