A pair of bpe-H(+) ligands in a zwitter-ionic complex undergoes photochemical cycloaddition quantitatively accompanied by proton transfer and the cyclobutane ring isomerizes slowly in solution to two more isomers, catalyzed by CF(3)CO(2)H acid.
两性离子络合物中的一对bpe-H(+)配体发生光化学环加成反应,定量地伴随质子转移,并且在CF(3)CO(2)H酸的催化下,环丁烷环在溶液中缓慢异构化为另外两种异构体。
