Abstract Cyclopentenone and dichlorocycloalkenes give [2+2] adducts whose stereochemistry (from modern NMR) is mostly cis, anti, cis; cis, syn, cis minor adducts are also found. Cophotolysis of dichlorocyclohexene and cycloheptanocyclopentenone does not give any adduct.
摘要 环戊烯酮和二氯环烯烃产生 [2+2] 加合物,其立体化学(来自现代核磁共振)主要是顺式、反式、顺式;还发现了顺式、顺式、顺式次要加合物。二氯环己烯和环庚基环戊烯酮的共光解不产生任何加合物。
