本文报道了一种控制金属中心电子密度的策略，该策略使用涉及第二球刘易斯酸结合的远程化学开关来调节第一配位球的电子密度。刘易斯酸B(C6F5)(3)在联吡嗪-二芳基铂（II）配合物的远氮位置结合，使联芳基的还原消除速度加快了64,000倍。
A strategy for the control of electron density at a metal center is reported, which uses a remote chemical switch involving second-sphere Lewis acid binding that modulates electron density in the first coordination sphere. Binding of the Lewis acid B(C6F5)(3) at remote nitrogen positions of a bipyrazine-diarylplatinum(II) complex accelerates biaryl reductive elimination by a factor of 64,000.
