Highly efficient catalytic asymmetric acylation of meso-1, 2-diols with benzoyl chloride in the presence of a chirai diamine combined with Et3 N. What is Benzoyl Chloride? Benzoyl Chloride is an acyl chloride derived from benzoic acid. Its chemical formula is C₆H₅COCl, and it is known for being highly reactive, especially with water and alcohols. Due to its reactivity, it serves as a key acylating agent in organic synthesis. Solid catalyst treated with anion: XVIII. Benzoylation of toluene with benzoyl chloride and benzoic anhydride catalysed by solid superacid of sulfate-supported alumina. High activity of iron containing metal-organic-framework in acylation of p-xylene with benzoyl chloride. Benzoyl chloride is an acyl chloride consisting of benzene in which a hydrogen is replaced by an acyl chloride group. It is an important chemical intermediate for the manufacture of other chemicals, dyes, perfumes, herbicides and pharmaceuticals.
