詳細

アプリケーション

クロスカップリングの触媒として、様々なパラジウム錯体と共に用いるかさ高いホスフィンです。

Di-tert-butylmethylphosphine (P^tBu₂Me) 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.
