Procedure

A mixture of 4 g of the pyrylium salt in 100 ml of acetone was stirred and 2 g of sodium sulfide in 50 ml of water is added. The solution was stirred for 1/2 hr and poured into dilute perchloric acid. The solid (which was the bis perchlorate salt) was dissolved in pyridine, the solution was diluted with alcohol and the solid which separated was collected, Mp 271°-272°, yield 3 g. The λmax (CH3CN) were 550 (58.0×103),~280 (17.0×103) and 265 nm (18.0×103).
