Abstract2-Aminopyridine-3-sulfonyl chlorides undergo a reaction with tertiary amines in the presence of air to produce sulfonylethenamines. The 2-aminopyridine-3-sulfonyl chloride apparently plays a dual role in the process promoting the aerobic oxidation of the amine and electrophilically trapping the resulting enamine.

Abstract Sodium borohydride reacts with sulfur in ammonia, primary, secondary or tertiary amines with hydrogen evolution to give the corresponding amine boranes, R3-nHnN-BH3. The reaction of sodium borohydride with carbon disulfide in the presence of a tertiary amine yields compounds R3N-BH3. The formulation of these reactions has been established by 11B and 1H NMR.
