  通过远程路易斯酸绑定到2,2'-Bipyrimidyl-Platinum复合物大大加快了Biaryl还原消除：明确的配体离解机制的证据。

  摘要：

  The silicon and zinc Lewis. acids Si(cat)(2) (cat = catecholato), Si(cat(F))(2) (cat(F) = tetrafluorocatecholato), and Zn(C6F5)(2) bind to the remote ligand site of a 2,2'-bipyrimidyl-platinum diaryl complex. This platinum complex provides a platform to systematically evaluate electronic and reactivity differences triggered by Lewis acid binding. The electron density of the bipyrimidine ligand is substantially depleted upon Lewis acid binding, as evidenced by UV-vis spectroscopy and cyclic voltammetry. Biaryl reductive elimination studies allowed quantification of the effect of Lewis acid binding on reactivity, and Lewis acid binding accelerated reductive elimination rates by up to 8 orders of magnitude. Kinetics experiments in combination with DFT studies support an unusual mechanism featuring complete dissociation of the Lewis acid coordinated bidentate bipyrimidine ligand prior to reductive elimination.

  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.
