Abstract

Herein we report isocyanatophosphoryl dichloride (the Kirsanov isocyanate) [5] as an easily accessible and convenient reagent for the introduction of a cyano group into electron-rich heterocycles and enamines. As was reported by us previously, the Kirsanov isocyanate dissolved in octane readily acylates electron-rich heterocycles to furnish, in good yields, N-dichlorophosphorylheterylcarboxamides. [6] Here we have found that the latter ...
