Vinyl isocyanate (3) and the novel 1‐chloroethyl isocyanate (2) are formed on heating the acid chloride (1) in the presence of α‐pinene. The increase in proportion of (3) in the product mixture as a function of the residence time could be explained in terms of an equilibrium between (2) and CH 3 CHNCOCl (X = Cl).
