Solvent- and Wavelength-Dependence of the Photocleavage of the Cyclobutane Ring in N,N'-Dibutyl-c-3,c-4-bis(2-hydroxyphenyl)-r-1,c-2-cyclobutanedicarboxamide

Article abstract of DOI:10.1246/bcsj.61.1005

The ratio between the photocleavage directions of the cyclobutane ring in the title compound varies with the solvent polarity and the irradiation wavelength, and the effect of the solvent polarity appears much larger in protic solvents than aprotic ones.
