使用铜（I）-氮配体催化剂如Ph/sub 3/PCuCl.bpy、Ph/sub 3/PCuCl.phen、Ph/sub 3/PCuCl.phtha和Ph/sub 3/PCuBr.py使得降冰片二烯到四环烷的光化学异构化能够在比350 nm更长的波长下进行，在该波长下CuCl催化剂本身不能诱导这种异构化。在带有各种发色团的降冰片二烯衍生物中，3-（苯基氨基甲酰基）降冰片二烯-2-羧酸在阳光下经历容易和定量的异构化成相应的四环烷衍生物。用催化量的Rh/sub ~ 2/（CO）/sub ~ 4/Cl/sub ~ 2/定量地进行四环烷反异构化为3-（苯基氨基甲酰基）降冰片二烯-2-羧酸。
Use of copper(I)-nitrogen ligand catalysts such as Ph/sub 3/PCuCl.bpy, Ph/sub 3/PCuCl.phen, Ph/sub 3/PCuCl.phtha, and Ph/sub 3/PCuBr.py enables the photochemical isomerization of norbornadiene to quadricyclane to be performed at a longer wavelength than 350 nm, at which CuCl catalyst itself cannot induce such an isomerization. Among the norbornadiene derivatives bearing various chromophores, 3-(phenylcarbamoyl)norbornadiene-2-carboxylic acid undergoes a facile and quantitative isomerization into the corresponding quadricyclane derivative in sunlight. The back-isomerization of quadricyclane to 3-(phenylcarbamoyl)norbornadiene-2-carboxylic acid proceeds quantitatively by use of catalytic amounts of Rh/sub 2/(CO)/sub 4/Cl/sub 2/.
