Application
在交叉偶联催化反应中与多种钯复合物一起使用的大体积膦。
Di-tert-butylmethylphosphine (PtBu2Me) when added as HBF4 salt, enhances the reactivity of palladium-catalyzed direct arylation of heterocylic arenes with aryl chlorides, bromides and azine N-oxides with aryl triflates to form the corresponding biaryl and 2-aryl azine N-oxides, respectively. It may be used in the preparation of CoCl2(PtBu2Me)2, a cobalt phosphine complex, which in combination with methylaluminoxane (MAO) catalyzes the butadiene polymerization to form predominantly the cis-1,4 polymer.
