Reaction of tetracyanoethylene with SCl2: new molecular rearrangements

Chemical Communications Pub Date: 2000-02-10 DOI: 10.1039/A909307I

Abstract

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 described; the products are derived from interaction of SCl2 with one cyano group with neighbouring group participation by two others.
