Reaction of polymerization resistant 1,2-dithiolanes 1 with excess pyridylmethyllithiums 3 in THF gave the corresponding ring-opened products 2 in good yields, but the by-products 2-pyridyl-1,3-dithianes 5 and 1,3-propanedithiols 6 could not be excluded. Addition of hexamethylphosphoric triamide (HMPT) to the reaction mixture resulted in the selective formation of 5.
