The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5-Iodo-2-furaldehyde, is researched, Molecular C5H3IO2, CAS is 2689-65-8, about Palladium-catalyzed synthesis of 4-heteroaryl and 4-alkynyl-substituted sydnones. 5-Oxido-3-phenyl-1,2,3-oxadiazol-3-ium-4-ylzinc chloride, the main research direction is palladium catalyzed coupling oxidophenyloxadiazoliumylcopper heteroaryl iodide; alkynyl bromide palladium catalyzed coupling oxidophenyloxadiazoliumylcopper; oxidophenyloxadiazoliumylzinc chloride preparation reactivity; sydnone heteroaryl alkynyl.COA of Formula: C5H3IO2.
A general method is suggested for the synthesis of 4-heteroaryl- and 4-alkynyl-3-Ph sydnones by palladium(0)-catalyzed cross-coupling of 5-oxido-3-phenyl-1,2,3-oxadiazol-3-ium-4-ylcopper (I, R = Cu) with heteroaryl iodides and alkynyl bromides. Thus, I (R = H) was treated sequentially with BuLi, CuBr, and then 2-iodopyridine and Pd(PPh3)4 in THF-C6H6 to give 85% I (R = 2-pyridyl). 5-Oxido-3-phenyl-1,2,3-oxadiazol-3-ium-4-ylzinc chloride (I, R = ZnCl) was synthesized and found to be significantly less reactive than I (R = Cu) and was successfully coupled only with p-iodonitrobenzene and β-bromostyrene.
