IC6H4-X or IH3-XY in organic solvents (dimethylacetamide, acetonitrile, methanol) using organic amines or potassium and sodium acetate as bases. If the primary phosphine is employed in the appropriate stoichiometric ratio, functionalized secondary phosphines, e.g. Ph(H)PC6H4-p-SO3Na, may be obtained selectively.
叔膦博士2 OAr和PHP(Ar)的2含有单-和disubtituded芳族环系的Ar(ArC 6 ħ 4 和C 6 HXY; X,YMe,OH,NH 2,COOH, COOMe和SO 3 Na)的是在良好的产率通过访问的Pd(O)催化的二苯基膦或苯基和取代的aryliodedsIC之间的交叉偶联反应6 ħ 4 -X或IH 3 -XY在有机溶剂(二甲基乙酰胺,乙腈,甲醇),以有机胺或乙酸钾和乙酸钠为碱。如果以适当的化学计量比使用伯膦,则官能化的仲膦,例如Ph(H)PC可以选择性地获得6 H 4 - p -SO 3 Na。
