Paragraph 0127-0131; 0257-0261, (2021/04/17)
The invention relates to a green synthesis method of polyaryl substituted methanol, in particular to a method for efficiently synthesizing polyaryl substituted methanol in a polar aprotic solvent under the condition of an oxidizing agent by taking polyaryl substituted methane as a raw material and alkali as an additive. The method provided by the invention is green and environment-friendly, avoids using expensive metal catalysts, and has the advantages of low cost, few reaction steps, short time, high yield and the like.

The efficient and selective iron-catalyzed C-H activation of 2-benzhydrylpyridine derivatives was employed for the preparation of pyrido[1,2-a]indoles through an intramolecular C-H amination reaction. In the presence of molecular oxygen as the sole oxidant, the same 2-benzhydrylpyridines were also used for the synthesis of the corresponding tertiary alcohols. In these approaches, the iron catalyst was used to selectively activate the C(sp2)-H bond of 2-benzhydrylpyridine, in the case of the intramolecular ring-closing C-H amination reaction in which the pyridine nitrogen atom was a directing group as well as a nucleophile, and the C(sp3)-H bond of the same compound, in the case of the oxidation reaction to give the corresponding triaryl carbinol.
