The Preparation of 2,4,6-Triphenylpyrylium Trifluoromethanesulphonate, Fluorosulphonate, Ethoxysulphonate, Naphthalene-2-sulphonate, Stannochloride, Trichloroacetate, and Trifluoroacetate and other Pyrylium Trifluoromethanesulphonates and their Reactions

The title pyrylium salts are all readily prepared in high yield from 1,3,5-triphenylpent-2-ene-1,5-dione.Amines react with the trifluoromethanesulphonate, naphthalene-2-sulphonate, and trifluoroacetate to give the corresponding pyridinium salts in high yi
