Abstract
The reaction of 3-aryl-2-cyano-5,5 -bis (methylthio)penta-2,4-dienenit rile, (1), with L-(-)-2-hydroxymethylpyrrolidine, (2), gave two types of product, the normal substitution product, (3), and a pyridine deriv ative, (4). The structures of two representative examples, c]-oxazol-3 -ylidene)-1-propene-1,1-dicarbonitrile, (3a), as its hemibenzene solva te, C17H15N3O.0.5C(6)H(6), and 4-(4-methoxyphenyl)-2,6-bis(methylthio) pyridine-3-carbonitrile, (4b), C15H14N2OS2, have been unambiguously e stablished by X-ray crystallographic analysis. The molecular packing o f (4b) involves loosely held dimers, with S1...S1' distances of 3.424( 1) Angstrom.
