Cycloheptatriene (CHT) is an organic compound with the formula C₇H₈. This colourless liquid has been of recurring theoretical interest in organic chemistry. It is a ligand in organometallic chemistry and as a building block in organic synthesis. Cycloheptatriene is not aromatic, as reflected by the nonplanarity of the methylene bridge (-CH₂-) with respect to the other atoms; however the related tropylium is.
A method for visible light-induced arene dearomatization backbone editing synthesis of novel [4,4,2,0] skeleton molecules
The present application relates to a kind of visible light induced aromatic compound occurs to edit the reaction of de-aromatic skeleton to synthesize novel tricyclo [4,4,2,0] skeleton molecule method. Specifically under the action of photocatalyst, N-acetyl imine generates double radical, and through double radical iteration produces de-aromatic cycloheptatriene type double radical intermediate, then with alkyne occurs the radical type cycloaddition reaction. The present application obtains a series of novel tricyclo [4,4,2,0] skeleton molecules by simple and safe step.
