The reactions of dimethylformamide with cyanogen chloride and with thionyl chloride have been studied, and several of the products identified by spectroscopic methods. As in the case of a previously reported reaction between dimethylformamide and cyanuric chloride, Vilsmeier adducts are formed. For the cyanogen chloride reaction a mechanism is put forward that accounts for the products more satisfactorily than would the cyanuric chloride ...
