Participants

Reaction Steps

A mixture of 3.1 g. of 2,6-bis(4-amyloxyphenyl)-4-methylpyrylium perchlorate, 2.0 g. of 2-(4-amyloxyphenyl)-6-phenyl-4-pyrone, and 20 ml. of acetic anhydride are stirred and heated at its boiling temperature for 5 to 10 minutes, cooled, diluted with ethanol with stirring, and chilled in a freezer. A solid separates from the mixture and is collected and washed with water. Another crop is obtained by adding water to the reaction mixture, extracting with dichloromethane, removing the solvent by evaporation, and recrystallizing the residue from acetic acid. The two crops are combined and recrystallized again from acetic acid. mp = 68°C. The theoretical values calculated for C50H55ClO, and the actual values found are as follows:
