Title:
ピリリウム塩の製造方法
Document Type and Number:
Japanese Patent JP7337818
Kind Code:
B2
Abstract:
The present invention relates to the process for the preparation of Pyrylium salts having the formula represented below. Present invention provide a simplified method of producing symmetrical and unsymmetrical pyrylium salts. The invention explores readily available starting materials with reaction conditions which are suitable for industrial scale applications. All the synthesized compounds were confirmed by various spectroscopic techniques such as Fourier transform infrared spectroscopy, 1H NMR, 13C NMR, 19F NMR spectroscopy, and single-crystal X-ray analysis. Mass of the compounds confirmed by HRMS analysis.
