## Abstract The alkyl‐substituted heterocyclic carbonitriles 1–3 react with elemental sulphur to yield the thienoazines 7, 11 and 13, respectively. Whereas 7 reacts with acrylonitrile to afford a [4+2] cycloaddition product with elimination of hydrogen sulphide, compounds 11 and 13 are not converte
