A Cu-catalyzed remote sp3 C-H/unactivated alkenes functionalization reaction for the concomitant construction of C-CF3 and C-O bonds was described. An 1,5-H radical transfer involving an sp3 C-H bond adjacent to a nitrogen atom and an α-CF3-alkyl radical intermediate derived from unactivated alkenes was observed and demonstrated to proceed via the radical process. C-CF3 formation/1,5-H radical shift/remote functionalization of sp3 C-H bond.

(Chemical Equation Presented) We have developed a Pd(II)-catalyzed oxidative tandem aminoalkylation via divergent C(sp3)-H functionalization, a ffording three- and five-membered-ring fused indolines in good yields under two optimized conditions, respectively. The mechanism studies have indicated that the benzylic C - H cleavage involved in the former transformation is the rate-determining step, while the cleavage of amide α-C - H in the latter is not. This is the first example of a Pd-catalyzed tandem reaction involving C(sp3)-H activation without the employment of prefunctionalized reagents (e.g., halogenated and boron reagents) and directing groups, representing a green and economic protocol for the construction of N-containing heterocycles.
Phosphine-catalyzed remote β-C-H functionalization of amines triggered by trifluoromethylation of alkenes: One-pot synthesis of bistrifluoromethylated enamides and oxazoles

Photoreactions of 1,2- and 1,4-dicyanobenzenes (o- and p-DCB) with allylic silanes, germanes, and stannanes in acetonitrile were studied under various conditions.In these photoreactions, one of cyano groups of o- and p-DCB was replaced by allylic groups.W
