The cyanamides 1 and 3 react with tertiary alkyl chlorides and antimony pentachloride affording formal heterocumulenes SbCl 6 − ( 2a , b ) and SbCl 6 − ( 4a , b ). X‐ray analyses of 2b and 4b reveal that in the crystal these compounds are bent pseudocumulenes having structural properties of nitrilium salts ( B ) and of carbodiimides ( D ). With amines and alcohols 2 and 4 react to give compounds 11 – 17 which are probably not amino‐substituted 2‐azaallenium salts E but guanidines F .
