Reaktionsschritte

2-Hydroxymethyl-3-methyl-thiophene (4.5 g.) was dissolved in 90 ml. of acetonitrile and 12.3 g. of triphenylphosphonium bromide were added. The reaction mixture was heated to 70° C. for 3 hours. After cooling the resulting precipitate was filtered off, washed with benzene and dried at 80° C. under high vacuum. The resulting (3-methyl-2-thenyl)triphenylphosphonium bromide has a m.p. 266°-269° C.
