Reaction:   CHBrClO(.) → HC(O)Br + ·Cl
Reaction order:   1
Rate expression:   no rate data available
Category:  Theory
Data type:   Ab initio
Comments:   No rate expressions reported. Energetics of pathways only.

Used ab initio method CCSD(T)/6-311+G(d,p) to explore reaction pathways for CHBrCl + O. Combination is barrierless to form halomethoxy species. Beta scission eliminations of Br and Cl atoms are possible, as are 1,1-elimination of HBr and HCl. Halomethoxy can also isomerize to hydroxymethyl species, which than can do 1,2-eliminations of HBr and HCl. See paper for details of energetics. CHBrCl + O -> CHBrClO
