Using the new P(O) t Bu2 Directed Metalation Group, a variety of ortho-substituted aryl di-t-butylphenylphosphine oxides (2a-k) have been prepared, its relative metalation ability has been established, and reduction and homocoupling products (Scheme 4) have been obtained.
利用新的 P(O) t Bu2 定向金属化基团,制备了多种正交取代芳基二叔丁基苯基膦氧化物(2a-k),确定了其相对金属化能力,并获得了还原和均偶产物(方案 4)。
