A novel protocol for Rh(III)-catalyzed switchable C-H acylmethylation and annulation of 2,2′-bipyridine derivatives with sulfoxonium ylides was reported. This protocol provided a facile approach to synthesize structurally diverse acylmethylated 2,2′-bipyridine derivatives I [R = i-Pr, Ph, 2-FC6H4, etc.; R1 = H, Me, Br, etc.; R2 = H, Br; R3 = H; R4 = H; R3R4 = CH=CH-CH=CH] and acyl-pyrido[2,3-a]indolizines II [R5 = Ph, 1-naphthyl, 2-furyl, etc.; R6 = H, Br, F, etc.; R7 = H, Br; R8 = H; R9 = H; R8R9 = CH=CH-CH=CH] with a broad range of functional group tolerance.
