It is clear therefore that a progressive change in the pa value of the hydrolytic reagent causes a progressive change in the nature of the reaction and this may be due to a progressive tautomeric change in the constitution of phenylthiocarbamide. [...] 4. In other words the carbon-sulphur bond is the first to be rutured in the presence of alkali the carbon-anilino in the presence of acids the carbon-amine in the presence of the strongest acids. [...] The yield of Hector's base (including the correponding amount of the base calculated from the quantity of the nitroso derivative formed) was 82-85% of that represented by equation (i) and the amount of mustard oil was about 10% of that represented by equation (ii). [...] Mustard oil was actually isolated to the extent of 66'576 of that represented by the equation C6H5NHCSNH2 + HNO2--->C6H5NCS +N2 + 2H20 and the amount of Hector's base was 23% of that required by the equation (i) The composition of the gas evolved was 80% nitrogen and 204) nitric oxide. [...] The smell of phenylisocyanide developed from the very start and became almost intolerable by the end of the experi' ment; a deep yellow precipitate of the nitroso derivative of Hector's base settled at the bottom of the beaker with some sticky mass resembling sulphur.
