• The role of entropic and electronic factors in controlling homo-1,4 addition of dihalocarbenes to norbornadiene-type molecules

  The proportion of 1,2 and homo-1,4 adducts obtained from the reaction of difluoro-carbene with norbornadiene and its 7-oxa, 7-methyl, and 7,7-difluoro derivatives is reflected by the calculated energies of the frontier molecular orbitals of the dienes. It appears that the product composition is dictated by competing 1,2 electrophilic and homo-1,4 nucleophilic cheletropic reactions.
