摘要: Bystander substituent effects in the 1,2-H shifts of several singlet alkylmethylcarbenes (CH2Y–C–CH3) have been studied using density functional theory. Bystander effects similar to that of alkylchlorocarbenes were observed. The methyl, halo, and phenyl groups accelerate 1,2-H shifts in the order Ph>F>Me>Cl, Br>H. Singlet/triplet energy separation of these carbenes have also been examined. All studied carbenes have singlet ground states, and the ability of Y groups to stabilize the relative energies of singlet states is F>Cl>Br>Ph>Me>H.
