Title:
MANUFACTURE OF AROMATIC CARBONYL COMPOUND
Document Type and Number:
Japanese Patent JPS6191151
Kind Code:
A
Abstract:
Aromatic carbonyl compounds, in particular arylene ether ketones, are prepared by reacting an appropriate reagent system in the presence of free Lewis acid and a complex between a Lewis acid; for example, aluminum trichloride, and a Lewis base, for example, N,N-dimethylformamide, and, optionally, a diluent, such as methylene chloride. The process is particularly advantageous for the preparation of substantially or all paralinked arylene ether ketones as the presence of the Lewis acid/Lewis base complex markedly reduces alkylation and ensures the substantial absence of ortho substitution.
