2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Related Products of 700-16-3

The extreme electron withdrawing properties of the perfluoropyridinoxy ligand -OC5F4N were used for the preparation of new (weakly) coordinating borate and aluminate anions [E(OC5F4N)4]– (E = B or Al). These new anions are based on the potent parent Lewis acids E(OC5F4N)3, which possess exceptionally high calculated F– ion affinities (FIAs) of 500 and 587 kJ mol-1 for E = B and Al, resp. For Al, this extreme Lewis acidity dominates the chem. and from mixtures of the neutral polymeric Lewis acid [Al(OC5F4N)3]n, the five- and six-coordinate complexes Al(OC5F4N)3(OEt2)2 (1) and [Al(OC5F4N)2(μ-OC5F4N)(NCMe)2]2 (2) were crystallized upon addition of ether or MeCN. The aluminate salts M[Al(OC5F4N)4] (M = Li or K) were prepared from the reaction between the alc. 4-HO-C5F4N and either LiAlH4 or K[AlEt4], resp. The aluminate anion [Al(OC5F4N)4]– remains Lewis acidic coordinating small donor mols. forming [Al(OC5F4N)4(L)]– (L = THF or NMe3) and even supports formation and structural characterization of the Al dianion containing salt [Na(OEt2)2][Na][Al(OC5F4N)5] (8). The from NaBH4 and 4-HO-C5F4N accessible borate salt Na[B(OC5F4N)4] shows increased kinetic stability in comparison to the Al analog. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Related Products of 700-16-3).
