Abstract

The thermal cyclisation of enediynes to benzene-1,4-diyl diradicals (Bergman cyclisations) is affected by geometrical and electronic conditions. While the effect of ring strain or conformational constrains on the cyclisation temperature has been investigated in detail, electronic contributions have been less studied. Often geometrical and electronic contributions cannot be clearly distinguished. ...
