The chloride ion catalysed addition of SCl2 to TCNE gives the dicyanomethylene-1,2,6-thiadiazine 3 as major product together with two unexpected minor products, pyrimidine 4 and pyrroloimidazothiadiazine 5, whose X-ray crystal structures are describedthe products are derived from interaction of SCl2 with one cyano group with neighbouring group participation by two others.
