Selective synthesis of valuable secondary amines through N-alkylation of amines with alcs. is an important reaction in the modern industry but still remains a challenge in the chem. synthesis technique. Hereby, we report the visible-light-driven photocatalytic N-alkylation of aniline with benzyl alc. over defined single Pd species in situ coordinated on a CdS surface. Encouragingly, an aniline conversion of 100% and an almost 100% product selectivity toward the secondary amine N-benzylaniline are obtained with impressive H2 production (11.8 mmol gcat-1 h-1). The mechanistic studies reveal that the single Pd-Sx species on the CdS surface can trap photogenerated electrons to endow them with a long lifetime to benefit the vibrational coupling of the hydrogen adsorption on Pd-Sx species and then can serve as an efficient hydrogen autotransfer shuttle for the hydrogenation process toward the formation of the secondary amine N-benzylaniline. In addition, the present catalyst possesses good substrate tolerance for photocatalytic N-alkylation of different alcs. and substituted amines under optimized conditions. This work offers an alternative solar-driven catalytic system for the N-alkylation industry under mild conditions. In the experiment, the researchers used many compounds, for example, (4-Chlorophenyl)methanol (cas: 873-76-7Quality Control of (4-Chlorophenyl)methanol).
(4-Chlorophenyl)methanol (cas: 873-76-7) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Quality Control of (4-Chlorophenyl)methanol
