organometallic reactions of secondary arsingalogenides

The experimental possibility of splitting asymmetric derivatives of three-and four-coordinated arsenic into optically active antipodes had for a long time remained unattainable for many well-known chemists, including meisenheimer (germany), kamai (russia), etc. when a racemic mixture of chiral arsines is cleaved with optically active components, a functional group (acidic or basic) is used that is contained in one of the fragments bound to the arsenic atom. chiral arsines containing a carboxyl group are synthesized by oxidation of the corresponding fragments. based on the results, to develop effective methods for the synthesis of tertiary arsines containing functional groups xc6h4(c2h5)asc6h4у, where у=о-, m-, p-nh2, cooh, the reactivity of ethylarylarsine chlorides with organometallic compounds should be considered.
