N,N-coordinate nickel (II) complexes with Schiff base ligands were synthesized. All N,N-coordinate nickel (II) complexes 1–4 were well characterized by IR and elemental anal. Mol. structure of 1 was further characterized by single crystal x-ray diffraction anal. All air and moisture stable nickel complexes showed efficient catalytic activity for the amidation reaction of a widely range of amides and primary alcs. N-alkylated amides were given in good to excellent yields with liberating water as the sole byproduct. A variety types of functional groups tolerated well in such reaction condition. Control experiments were carried out to understand this Ni-catalysis protocol. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Related Products of 105-13-5).
(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Related Products of 105-13-5
