Dihydrofuran ring opening in the reactions of 2,3-dihydrofuro[3,2-c] coumarin-3-one with arylhydrazines

2,3-Dihydrofuro[3,2-c]coumarin-3-one reacts with arylhydrazines via two routes. The corresponding hydrazones are formed from arylhydrazines in alcohol and nitrophenylhydrazines in acetic acid or toluene. With phenylhydrazine and para-tolylhydrazine in toluene, 2,3-dihydrofuro[3,2-c]coumarin-3-one reacts unusually undergoing dihydrofuran ring opening and the formation of the corresponding 3-(2-imino-1-(2-arylhydrazinyl)ethylidene)-chromane-2,4-diones. The solvatochromic properties of the synthesized compounds were studied using electronic absorption spectra and quantum chemical calculations.
