Chalcogen Bonded Directly To Ring Carbon Of The Diazole Ring Patents (Class 548/366.1)
- The nitrogen is multiply bonded to acyclic carbon or is bonded to nitrogen of the diazole ring (Class 548/367.7)
- Chalcogen attached directly to the nitrogen by nonionic bonding [e.g., 5- (2-carbethoxyphenoxy)-1,3-dimethyl-4-nitropyrazole, etc.] (Class 548/368.1)
- Having -C(=X)-, wherein X is chalcogen, bonded directly to the nitrogen (Class 548/368.4)
- The nitrogen and the chalcogen are directly bonded to non-adjacent carbons of the diazole ring (e.g., pyrazolone imide or imino pyrazolone, etc.) (Class 548/368.7)
- Chalcogen attached indirectly to the nitrogen by acyclic nonionic bonding (Class 548/369.1)
