Abstract

Salts of the weakly coordinating anions [Ga(OTeF ) ] as well as [Ga(Et)(OTeF ) ] and the neutral Ga (Et) (OTeF ) were synthesized and characterized by spectroscopic methods and single-crystal X-ray diffraction. Ga (Et) (OTeF ) was formed by treating GaEt with pentafluoroorthotelluric acid (HOTeF ) and reacted with PPh Cl and CPh Cl to [PPh ][Ga(Et)(OTeF ) ] and [CPh ][Ga(Et)(OTeF ) ]. In contrast, Ag[Ga(OTeF ) ] was prepared from AgOTeF and GaCl and was used as a versatile starting material for further reactions. Starting with Ag[Ga(OTeF ) ] the substrates [PPh ][Ga(OTeF ) ] and [CPh ][Ga(OTeF ) ] were formed from PPh Cl and CPh Cl.

摘要

合成了弱配位阴离子[Ga(OTeF ) ]以及[Ga(Et)(OTeF ) ]的盐类和中性的Ga (Et) (OTeF )，并通过光谱方法和单晶X射线衍射对其进行了表征。Ga (Et) (OTeF )是通过用五氟原碲酸（HOTeF ）处理GaEt形成的，并与PPh Cl和CPh Cl反应生成[PPh ][Ga(Et)(OTeF ) ]和[CPh ][Ga(Et)(OTeF ) ]。相比之下，Ag[Ga(OTeF ) ]是由AgOTeF和GaCl制备的，并用作进一步反应的通用起始原料。以Ag[Ga(OTeF ) ]为起始原料，由PPh Cl和CPh Cl形成了底物[PPh ][Ga(OTeF ) ]和[CPh ][Ga(OTeF ) ]。
