as chlorinating agents and oxidants. 1 Their properties are similar to those of N-chloroamines, which, however, are less stable. A few of them are also common- ly used as chlorinating reagents and oxidants in organic synthesis: since chloroamines are easier to handle than chlorine gas or metal hypochlorites, they are widely used in organic synthesis in addition to their use in the purifi- cation of water

Reactions of (μ-PhPLi)2Fe2(CO)6 with various organic mono- and di-halides resulted in alkylation of the phosphorus atoms. The use of α,ω-dihalides gave products with an organic bridge between the two phosphorus atoms. Deprotonation of the complex where the organic bridge is an o-xylylene group at 20°C gives an anion (16) which undergoes a novel rearrangement via intramolecular attack at an iron atom
(μ-PhPLi)2 Fe 2(CO)6与各种有机一卤化物和二卤化物的反应导致磷原子烷基化。使用α,ω-二卤化物得到在两个磷原子之间具有有机桥的产物。在20°C下,有机桥键为邻亚二甲苯基的配合物的去质子化反应得到的阴离子(16)会通过分子内对铁原子的攻击而发生新的重排,从而生成19。

with tandem mass spectrometry (MSn), are used to study the mechanism of chlorination of amines and to develop a method for qualitative and quantitative determination of organic chloramines. Cyclohexylamine and 1,4-butanediamine (putrescine) are used as model compounds to investigate the mechanisms of the reactionsbetween primary aliphaticamines and hypochlorous acid (aqueous Cl2). The chlorination products
