A new radical condensation reaction is developed where benzylic alcohols and acetamides are coupled to generate 3-arylpropanamides with water as the only byproduct. The transformation is performed with potassiumtert-butoxide as the only additive and gives rise to a variety of 3-arylpropanamides in good yields. The mechanism has been investigated experimentally with labelled substrates, trapping experiments

The α-alkylation reaction of acetamides with primary alcohols to afford the corresponding amides was accomplished effectively using RuHCl(CO)(PPh3)3 as a catalyst, nitrogen tridentate ligand L1 as an additive, and KOtBu as a base. While the addition of bpy was effective only for benzylic alcohols, L1 affected the alkylation reaction when both benzylic and non-benzylic type alcohols were used.

geometry-constrained tridentate N,N,O-nickel complex for selective α-alkylation of unactivated amides using readily available alcohols as the alkylating reagents. The newly developed transformation could accommodate a broad substrate scope including various substituted benzylic or aliphatic alcohols and tertiary/secondary acyclic amides or lactams. The tolerance of methanol and ethanol in this protocol provided a novel
