Efficient alkylations of amines by alcohols catalyzed by well-defined Co(II) complexes are described that are stabilized by a PCP ligand (N,N′-bis(diisopropylphosphino)-N,N′-dimethyl-1,3-diaminobenzene) based on the 1,3-diaminobenzene scaffold. This reaction is an environmentally benign process implementing inexpensive, earth-abundant nonprecious metal catalysts and is based on the acceptorless alcohol dehydrogenation concept. A range of primary alcohols and aromatic amines were efficiently converted into mono-N-alkylated amines in good to excellent isolated yields.

, p. 5058 - 5061 (2015/01/08)
An efficient and regioselective bromination of 2-aminopyridines was developed. The environmental friendly bromination occurs under mild and clean conditions using readily available 1-butylpyridinium bromide as the bromine source and hydrogen peroxide as the green oxidant.
