Sulfoximidoyl radical. Homolytic addition of n-halosulfoximides to olefins

Homolytic addition reaction of N-halosulfoximides, i.e., diphenyl-N-chloro sulfoximide($\text{1}$), diphenyl-bromosulfoximide($\text{2}$), and methylphenyl-N-chloro-sulfoximide($\text{3}$), to such olefins as tert-butylethylene and cyclohexene was found to afford the corresponding N-alkylated sulfoximides, which are presumed to be formed via the initial addition of the sulfoximidoyl radical.
