Article abstract of DOI:10.1039/c39910001702

The seeming difference in the topochemical <2 + 2> photoreactivity of 3-cyanocinnamic acid 1 and 4-cyanocinnamic acid 2 is caused by differing degrees of ease of molecular motion in the crystals and the unreactive 1 becomes reactive when heated to 130 deg
