Abstract
The photocatalytic coupling of ethers is uncommon because of the challenges in breaking C-O bonds and low selectivity. Herein, we report a visible light-mediated deoxygenation homocoupling of benzyl pyridyl ethers via their pyridium salts. This approach enables C(sp3)-O bond homolysis under mild conditions. Mechanistic experiments support the radical nature of the reaction. This method is highly compatible with electron-withdrawing groups and has potential applications for drug precursor synthesis.

Abstract
AbstractDibenzyls are essential building blocks that are widely used in organic synthesis, and they are typically prepared by the homocoupling of halides, organometallics, and ethers. Herein, we report an approach to this class of compounds using alcohols, which are more stable and readily available. The reaction proceeds via nickel-catalyzed and dimethyl oxalate assisted dynamic kinetic homocoupling of benzyl alcohols. Both primary and secondary alcohols are tolerated.

Abstract
A novel three-component reaction was developed via a one-pot strategy for the construction of diarylmethanol esters by using a halobenzene and an ester in N,N-dimethylformamide (DMF) under mild conditions. The reaction involves the direct functionalization of halobenzene under the Sm-CuI catalyst system. It was proved that 10% (mol) of CuI is sufficient to realize the reductive coupling reaction. Influences of substituents were illustrated from both electronic and steric effects. The reaction mechanism was also discussed.

Abstract
Grignard-type additions were readily achieved under the mediation of CuI (10 mol%) and samarium (2 equiv.) by employing various organohalides, e.g. benzyl, aryl, heterocyclic and aliphatic halides (Cl, Br or I), and diverse carbonyl compounds (e.g. carbonic esters, carboxylic esters, acid anhydrides, acyl chlorides, ketones, aldehydes, propylene epoxides and formamides) to afford alcohols, ketones and aldehydes, respectively, with high efficiency and chemoselectivity, in which the organosamarium intermediate might be involved.
