Nitrogen-14 and chlorine-35-quadrupole resonance in some N-(1-chloro-2,4-diazabut-3-enylidene)-N,N-dimethylammonium salts

摘要: Nitrogen-14 and chlorine-35 quadrupole resonance frequencies have been measured at room temperature for a series of six closely related N·(1-chloro-2,4-diazabut-3-enylidene)-N,N-dimethylammonium salts two compounds. Reasonable assignments all 14N made their variations with structure are discussed. The results support the R1NCR2-NH–CClNMe2X– examined; it appears to be predominant from, cation has therefore named on this basis.
