Solid-state photodimerization of 1,2-bis(5′-pyrimidyl)ethene

Abstract

The photodimerization of 1,2-bis(5′-pyrimidyl)ethene in the solid state is reported. Photolysis of the crystalline solid formed on self-assembly of 1,2-bis(5′-pyrimidyl)ethene and C-methylcalix[4]resorcinarene and photolysis of the solid recystallized from dichloromethane yielded cis-anti-cis-1,2,3,4-tetrakis(5′-pyrimidyl)cyclobutane as the only product. Single-crystal X-ray analysis of each of these solids confirms that the alkenes are π-stacked, colinear, and separated by less than 4.2 Å.
