- This method is applicable to a wide range of substituted multilayered cyclophanes
- The absence of the inhibitor resulted in extremely poor yield because of increasing polymerization
- Too long time of the irradiation tended to decrease the yield
- The preparation of all the ammonium salts 7–11 was described in reference 3)
