Radicals masquerading as electrophiles: Dual orbital effects in nitrogen-philic acyl radical cyclization and related addition reactions

Article Abstract:

Nucleophilic radicals with low lying unoccupied orbitals such as acyl, oxyacyl, silyl, stannyl and germyl radicals are studied. These radicals are able to mask as electrophiles through singly occupied molecular orbital and highest occupied molecular orbital-lowest unoccupied molecular orbital interactions during these reactions and provide high levels of regiocontrol and efficient methods for the synthesis of important heterocycles.

Heterogeneous reactions important in atmospheric ozone depletion: A theoretical perspective

Article Abstract:

Theoretical studies of the mechanisms of several heterogeneous reactions involving CIONO(sub 2), H(sub 2)O, HCl, HB(sub r), and H(sub 2)SO(sub 4) important in atmospheric ozone depletion are described, focusing primarily on reactions on aqueous aerosol surfaces. The theory begins to provide significant insights for a variety of heterogeneous reactions crucial for atmospheric ozone depletion.
