Web500 nm. The decomposition process is now well established and involves either a heterolytic or homolytic cleavage of the C-I or C-S bond that forms e.g., a singlet phenyliodide/phenyl cation pair or a phenyliodinium cation/phenyl radical, respectively. Then, in-cage or/and an out-of-cage process arises.

The key difference between homolytic and heterolytic bond dissociation energy is that … In chemistry, bond cleavage, or bond fission, is the splitting of chemical bonds. This can be generally referred to as dissociation when a molecule is cleaved into two or more fragments. In general, there are two classifications for bond cleavage: homolytic and heterolytic, depending on the nature of the process. The triplet and singlet excitation energies of a sigma bond can be used to determine if a bond will follow the homolytic or heterolytic pathway. A metal−metal sigma bond i…
