The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5-(4-Pyridyl)-1H-tetrazole, is researched, Molecular C6H5N5, CAS is 14389-12-9, about (E)-1,2-Bis(5-aryl-1,3,4-oxadiazol-2-yl)ethenes, the main research direction is ethylenebisoxadiazole preparation; oxadiazole ethylenebis preparation; tetrazole fumaroyl chloride Huisgen.HPLC of Formula: 14389-12-9.
The title compounds (I) were prepared by acylation of the corresponding tetrazoles with fumaryl chloride and subsequent thermal ring transformation. The modified Huisgen reaction renders a new pathway to 3-(1,3,4-oxadiazol-2-yl)propenoic acids and subsequently to I with different substituents.
Compounds in my other articles are similar to this one(5-(4-Pyridyl)-1H-tetrazole)HPLC of Formula: 14389-12-9, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
