Unprecedented visible light-initiated topochemical [2 + 2] cycloaddition in a functionalized bimane dye

Unprecedented visible light-initiated topochemical [2 + 2] cycloaddition in a functionalized bimane dye

Bimanes, a class of molecules based on the 1H,7H-pyrazolo[1,2-a]pyrazole-1,7-dione scaffold, were first introduced by E. M. Kosower in 1978. In this study, we report the topochemical cycloaddition of diethyl 2,6-dichloro-1,7-dioxo-1H,7H-pyrazolo[1,2-a]pyrazole-3,5-dicarboxylate (Cl2B), initiated by...
