Abstract
1,3-Teraryls 2 were synthesised by reaction of l-3-methoxycarbonyl-4-( methylthio)-2H-pyran-2-ones 1a with aryl methyl ketones. An analogous reaction with 6-aryl-3-cyano-4(methylthio)-2H-pyran-2-ones 1b and aryl methyl ketones failed to yield cyano-substituted 1,3-teraryls, but af forded (4,6-diarylpyran-2-ylidene)acetonitriles 4 in poor yields.
