Dibromo-2,2’:6’2’’-terpyridine was obtained in a moderate yield by lithiation of four molar amounts of 2,6-dibromopyridine with butyllithium followed by treatment with phosphorus trichloride in diethyl ether.

characteristics and donor/acceptor properties of a series of 2-pyridyl substituted phosphine ligands have been investigated using structural, spectroscopic and DFT calculational studies. A range of different coordination modes are observed in Mo and W carbonyl complexes of tris-2-pyridyl-phosphine ligands of the type P(2-py') (2-py' = substituted or unsubstituted 2-pyridyl group), including an unprecedented

circumventing the use of PCl3. We use p-block element compounds of type RnE (for example, Ph3As or PhI) to access weak adducts between nitrogen Lewis bases LN and the corresponding dications [RnELN]2+. The proposed equilibrium between [RnELN]2+ + LN and [RnE(LN)2]2+ allows for the complete oxidative onioation of all six P–P bonds in P4 to yield highly reactive and versatile trications [P(LN)3]3+.
用于工业和研究的增值磷化学品的主要原料是白磷(P 4),其中形成 P(III) 化合物的关键中间体是 PCl 3。由于其高反应性,基于 PCl 3的合成通常伴随着产物混合物和费力的后处理程序,因此需要一种替代方法来形成可行的 P(III) 转移试剂。我们的氧化氧化概念,其中白磷被选择性地转化为多功能 P 1转移试剂的三氟甲磺酸盐,例如 [P(L N ) 3 ][OTf] 3 (L N是阳离子、N基取代基;即,4-二甲氨基吡啶),为实现 P-O、P-N 和 P-C 键提供了一种方便的替代方案,同时避免了 PCl 3的使用。我们使用 R n E类型的 p 嵌段元素化合物(例如,Ph 3 As 或 PhI)来获得氮路易斯碱 L N和相应的双阳离子 [R n EL N ] 2+之间的弱加合物。[R n EL N ] 2+ + L N和 [R n E(L N ) 2 ] 2+之间的拟议平衡允许 P 4中所有六个
