Abstract

SCRF calculations on transition structures of cycloadditions of acrylonitrile and maleonitrile to cyclopentadiene and 1,3-butadiene show that the experimentally observed endo preference for the cycloaddition of acrylonitrile to cyclopentadiene is the consequence of solvent influence and not the result of secondary orbital interactions.
