Abstract: | New Sulfinyl and Carbonyl Pseudohalogen Compounds FSO(NCO) ( 1 ) is formed as well during the attempt of synthesizing fluoroformyl sulfinylimide from OCFBr and Hg(NSO)2 by an unexpected rearrangement as from OSFCl and Hg(NCO)2 directly. FSO(NSOF2) ( 2 ) was obtained analogously. Trying to get OS(NCO)2, OC(NCO) (NSO) ( 3 ) was formed again by rearrangement as well as from ClCO(NCO) and Hg(NSO)2. |
