ãSelective transition metal-free aroylation of diarylmethanes with 2-acyl-imidazolium salts via acyl C-C bond cleavageã?was written by Zou, Dong; Gan, Li-She; Yang, Fan; Wang, Jia-Min; Li, Lin-Lin; Li, Jie. Formula: C5H6BNO2This research focused ontriarylethanone preparation chemoselective; acyl imidazolium salt diarylmethane aroylation. The article conveys some information:
A highly chemoselective method is reported for the aroylation of simple diarylmethane derivatives Ar1CH2Ar2 (Ar1 = pyridin-4-yl, pyridin-3-yl, furan-2-yl, furan-3-yl, 1-benzofuran-2-yl; Ar2 = Ph, 2-methylphenyl, 4-methoxyphenyl, naphthalen-1-yl, etc.) via direct acyl C-C cleavage with 2-acyl-imidazolium salts I (Ar3 = Ph, 3-methylphenyl, furan-2-yl, naphthalen-2-yl) under transition metal-free conditions. This represents a straightforward way to access a variety of sterically and electronically diverse 1,2,2-triarylethanones Ar3C(O)CHAr1Ar2, a class of compounds with biol. activities and various applications. In the experiment, the researchers used Pyridin-3-ylboronic acid(cas: 1692-25-7Formula: C5H6BNO2)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.Formula: C5H6BNO2
