摘要

The 3-trifluoromethyl derivatives of benzyl alcohol, benzyltrimethylsilane and phenoxytrimethylsilane undergo 2, 6-photocycloaddition to cyclopentene to give the 1, 11- disubstituted-tetracyclo [6.3. 0.02, 11.03, 7] undec-9-enes 7, 10, 11 and 12. This specificity in isomer formation is considered to originate from an intramolecular attractive interaction between the 1, 3-substituents on the arenes during the addition of the ethene and this ...
