摘要

Photocyclodehydrogenation of trans-9-styryl-1, 2, 3, 4, 5, 6, 7, 8-octahydroanthracene in cyclohexane solution formed a mixture of 11-butyl-and 11-but-3-enyl-1, 2, 3, 4- tetrahydrochrysene in very small yield, identified by their ir, uv, 1H nmr, and mass spectra. 2, 4, 6-Trimethylstilbene photocyclised to 1, 3-dimethylphenanthrene with the elimination of a methyl group. 3, 3′, 5, 5′-Tetramethylstilbene formed 2, 4, 5, 7- ...
