A Pd(II)-catalyzed oxidative alkoxycarbonylation of phenol derivatives with atmospheric pressure of CO–O2 and alcohols has been achieved. The reaction provides an efficient strategy for the synthesis of carboxylic esters and can be applied to the late-stage modification of complex molecules.
The nickel‐catalyzed borylation of aryl2‐pyridyl ethers via the loss of a 2‐pyridyloxy group is described. This method allows a 2‐pyridyloxy group to be used as a convertible directing group in C−H bond functionalization reactions. The nickel catalyst can also borylate arylmethyl 2‐pyridyl ethers, in which the stereochemistry at the benzylic position is retained in the case of chiral secondary benzylic
