A new method for the preparation of allylic alcohol derivatives has been developed via a radical mechanism using DTBP as the radical initiator promoted by copper salt. The C(sp(3))-H bond in various alcohols, toluene derivatives, and alkanes were successfully converted into C-C bonds to yield the desired products in moderate to good yields.

Iridium‐Catalyzed 1,3‐Rearrangement of Allylic Alcohols
An efficient Ir(III) dihydride complex catalyzed 1,3-rearrangement of allylicalcohols was realized, affording the corresponding less easily accessible allylicalcohols regio- and stereoselectively in high yields from readily available starting materials. The reaction pathway involves a π-allyl-Ir(V) intermediate and the dihydride in Ir(III) dihydride complex acts as the hydrogen switch to modulate
