## Abstract The coupling reactions of two diazotized 3βaminothieno[3,4βc]coumarins were investigated. Compounds **1a**, **1b** both react with sodium nitrite in concentrated sulphuric acid at 0β5Β°C to give the diazotized intermediates **2** and **3**, the latter resulting from the acid βcatalyzed h
