Regioselective Hula-twist photoisomerization of cinnamate esters in organic glass.
Irradiation of ethyl cis-o-fluorocinnamate and related compounds in organic glass led to two HT-isomerization processes that exhibit a strong preference at C-beta than at C-alpha as shown by low temperature UV absorption spectroscopy and supported by ab initio calculations.
