2-Alkylthiopyrylium salts are available in good yields via Aldol condensation reaction of β-chlorovinylaldehydes (carbonyl component) with acetone or α-methylene ketones (methylene component) followed by nucleophilic substitution reaction of the chlorine atom in the 4-acyl-1-chloro-1,3-butadienes by means of sodium sulfide and further cyclization of the resulting 4-acyl-1-mercapto-1,3-butadienes.
