Abstract

Results Addition of 8-Dicarbonyls to Cyanogen Catalyzed by Zn (acac)* Addition of catalytic amounts of Zn (aca~)~ to solutions of various 0-dicarbonyls (hereafter referred to as H-0-dic) in toluene containing C2Nz in comparable concentration leads to ready formation of adducts of stoichiometry HP-dic. C2N2. Most of these products precipitate spontaneously as white, crystalline, and very pure materials.
