| titleOfInvention | Process for the preparation of pyrylium salts |
| abstract | R = identique ou différent; H, alcoyle R 1 , R 2 = alcoyle X = halogène M = Al, Fe Process for the preparation of a polyalkyl pyrylium salt comprising at least 3 alkyl residues in position 2, 4, 6, by reacting a branched alkane comprising at least one tertiary carbon atom with an alkanoyl halide or an anhydride alkanoic acid and an alkyl halide, in the presence of a Lewis acid, according to the probable scheme. R = identical or different; H, alkyl R 1 , R 2 = alkyl X = halogen M = Al, Fe n n n Pyrylium salts can be used to prepare alkylpyridines and dialkoylphenols. |
