Synthesis of Alkynylthiopyridinium Salts and Their Use as Thioketene Equivalents

A synthetic method has been developed for the preparation of dihalo(pyridinium)sulfuranes and their transformation into alkynylthiopyridinium salts, starting from inexpensive thiopyridones. The reactivity of these salts towards different nucleophiles is evaluated. Most thiols and amines are converted into dithioesters and thioamides, respectively; whereas sterically demanding thiols delivered alkynylthioethers. These results, together with preliminary mechanistic studies reveal that alkynylthiopyridinium salts can be considered synthetic equivalents of unstable thioketenes.

On the ring-contraction of 1,4-dithiins to 1,3-dithiole derivatives

The effect of different factors (pKa of the base, nature of the counterion and dissociation of the ion pairs) on the course of the base-induced rearrangement of 1,4-dithiins to 1,3-dithiole derivatives is discussed. Ab initio calculations account for the driving force of these isomerisations.

1-Alkynyl Disulfides: Their Characterization and Their 1-Thiapropargyl-3-Thiaallenyl Rearrangements

The synthesis of novel 1-alkynyl disulfides 1 is described together with their 1-thiapropargyl-3-thiaallenyl rearrangement and a -sigmatropic shift of 1-alkynyl amino disulfides, followed by rearrangement of the aminothio-substituted thioketenes so formed.
