Conversion of primary aliphatic amines into thiocyanates and thiocarbonate esters

Abstract
2,4,6-Triphenylpyrylium thiocyanate converts primary aliphatic amines into 1-substituted-2,4,6-triphenylpyridinium thiocyanates which smoothly pyrolyse to 2,4,6-triphenylpyridine and the corresponding alkyl thiocyanate; 1-substituted-2,4,6 triphenylpyridinium perchlorates give S-alkyl O-ethyl dithiocarbonates with potassium ethyl xanthate.
