Primary amines when warmed with alcoholic carbon disulphide followed by heating with excess of mercuric chloride form isothiocyanates having pungent smell similar to mustard oil.
Secondary amines also react with CS2 to form dithiocarbamic acids, but the latter do not react with mercuric chloride
R2NH + S = C = S → S=C(SH)NR2
Tertiory amines do not react with carbon disulphide.
