Allyl thiocyanate, isomerisation

For example, degradation of the most common glucosinolate, sinigrin, yields, in addition to allyl isothiocyanate (see Section 8.2.9.1.5) and allyl cyanide (but-3-enenitrile, see Section 8.2.7.1.3), allyl thiocyanate (it is not clear whether this substance arises directly from the unstable aglycone or by isomerisation of isothiocyanate) and 2-(cyanomethyl)thiirane, also known as... 

It can be prepared artificially by the action of allyl iodide on an alcoholic solution of thiocyanate of potassium, the latter body being isomerised to the isothiocyanate under the influence of heat.
