A process for efficiently producing, through few steps either a xanthine oxidase inhibitor, which is a therapeutic agent for hyperuricemia, or an intermediate therefore. The process is a novel coupling process which comprises subjecting a compound represented by formula (1) to coupling reaction with a compound represented by formula (2) in the presence of a transition metal compound to thereby obtain a compound represented by formula (3).
Routes to compounds with one or more t-butyl groups directly attached to phosphorus have been explored, and a number of new compounds of this type have been prepared. Reduction of t-butylphosphonothioic dichloride with triphenylphosphine provides a route to t-butylphosphonous dichloride which, although having more stages than that previously described, may be advantageous for large scale operation
已经探索了具有直接与磷连接的具有一个或多个叔丁基的化合物的途径,并且已经制备了许多这种类型的新化合物。用三苯基膦还原叔丁基硫代硫代二氯化物提供了通往叔丁基二氯代磷的途径,尽管其步数比先前所述的多,但对于大规模操作而言可能是有利的。当叔丁基基团连接到磷Arbusov反应和其他一些普通的有机磷反应抑制,但的叔丁基氯以烷基亚膦二氯化物反应(RPCL 2 ; R =甲基,乙基,镨我,或卜吨)为烷基叔丁基次膦酰氯提供了良好的路线,从而为相应的酸提供了良好的途径。红外波段在805至835厘米之间。–1是叔丁基磷化合物的特征。

Paramagnetic rhodium(II) complexes of the type trans-[RhCl2(PBut2R)2](R = Me, Et, or Prn) are formed rapidly by treating ethanolic rhodium(III) chloride trihydrate with the tertiary phosphine at 25 °C. The complexes have low magnetic moments in the solid state (<1·4 B.M.) but in solution trans-[RhCl2(PBut2Me)2] has the expected moment of ca. 2·12 B.M. Treatment of rhodiumtrichloride trihydrate with some t-butylphosphines
