A straightforward protocol for the preparation of N,N-dimethylated amines from readily available nitro starting materials using formic acid as a renewable C1 source and silanes as reducing agents was reported. This tandem process was efficiently accomplished in the presence of a cubane-type Mo3PtS4 catalyst. A [3+1] building block strategy starting from the trinuclear [Mo3S4Cl3(dmen)3]+ and Pt(PPh3)4 complexes was followed for the preparation of the novel [Mo3Pt(PPh3)S4Cl3(dmen)3]+ (dmen: N,N’-dimethylethylenediamine) compound. The heterobimetallic [Mo3Pt(PPh3)S4Cl3(dmen)3]+ cation preserved the main structural features of its [Mo3S4Cl3(dmen)3]+ cluster precursor. Interestingly, this catalytic protocol operated at room temperature with high chemoselectivity when the [Mo3Pt(PPh3)S4Cl3(dmen)3]+ catalyst co-exists with its trinuclear [Mo3S4Cl3(dmen)3]+ precursor. N-heterocyclic arenes, double bonds, ketones, cyanides and ester functional groups were well retained after N-methylation of the corresponding functionalized nitroarenes. In addition, benzylic-type as well as aliphatic nitro compounds were also methylated following this protocol. In the experiment, the researchers used many compounds, for example, 2-Chloro-N,N-dimethylaniline (cas: 698-01-1Quality Control of 2-Chloro-N,N-dimethylaniline).
2-Chloro-N,N-dimethylaniline (cas: 698-01-1) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Quality Control of 2-Chloro-N,N-dimethylaniline
