3H‐1,2‐Dithiolo[3,4‐b ]pyridine‐3‐thione (10 ) reacts with primary alkylamines to give 1,2‐dihydro‐2‐thioxo‐3‐pyridinecarbothioamides 11a‐g and two minor products. Isothiazolo[5,4‐b ]pyridine‐3(2H )‐thiones 12a‐g and 3‐imino‐3H‐1,2‐dithiolo[3,4‐b ]pyridines 13a‐g were isolated and characterized. Further investigations allowed the synthesis of 12 and 13 in good yield.

Abstract
3H‐1,2‐Dithiolo[3,4‐b ]pyridine‐3‐thione (10 ) reacts with primary alkylamines to give 1,2‐dihydro‐2‐thioxo‐3‐pyridinecarbothioamides 11a‐g and two minor products. Isothiazolo[5,4‐b ]pyridine‐3(2H )‐thiones 12a‐g and 3‐imino‐3H‐1,2‐dithiolo[3,4‐b ]pyridines 13a‐g were isolated and characterized. Further investigations allowed the synthesis of 12 and 13 in good yield.File in questo prodotto:
