Selective C(sp2)-H bond alkylation of indoline like 2,3-dihydro-1-(2-pyridinyl)-1H-indole, carbazole like 9-(2-pyridinyl)-9H-carbazole and (2-pyridinyl)arenes I (R1 = H, 4-Me, 4-OMe, 3-F3C) with unactivated alkyl bromides R2(CH2)2Br (R2 = Et, Pr, 4-(9H-carbazol-9-yl)butyl, etc.) is achieved using MnBr2 catalyst in the absence of an external ligand. The alkylation uses a simple LiHMDS base and avoids the necessity of Grignard reagent, unlike other Mn-catalyzed C-H functionalization. This reaction proceeded either through a five- or less-favored six-membered metallacycle, and tolerated diverse functionalities, including alkenyl, alkynyl, silyl, aryl ether, pyrrolyl, indolyl, carbazolyl and alkyl bearing fatty alc. and polycyclic-steroid moieties. Alkylation follows a single electron transfer (SET) pathway involving 1e oxidative addition of alkyl bromide and rate-limiting C-H metalation.
