Abstract

The structure of 3-mercapto-6(1H)-pyrida:dnethione is discussed.
On the basts of spectroscopic evidence and pK values,
structure (I) is proposed, with an important contTibution of the
dipolar character. Some addition reactions on unsaturated systems,
e.g. acrylonitrile, ethyl acrylate and cyclopentadiene, were performed
affording invariably S-alkylated derivatives.
