Weakly coordinating anions WCAs

The SbFg anion was one of the first examples of a weakly coordinating anion (WCA) or superweak anion, an anion so unreactive as to coexist in a salt with a simple, highly reactive carbocation. Chemists could scarcely believe this feat had been accomplished. Olah realized that carbocations such as r-butyl may also reversibly eliminate H to form alkenes ... [Pg.240]

Krossing, Ingo, and Ines Raabe. Noncoordinating Anions Fact or Fiction A Survey of Likely Candidates. Angewandte Chemie International Edition 43 (2004) 2,066-90. This is an in-depth review of weakly coordinating anions (WCAs) and the cations whose isolation they enable. [Pg.404]

Use of extremely weakly coordinating anions (including several based on carboranes, whose structures we will not discuss for reasons of space), hereafter simply referred to as [WCA] , allows the synthesis of even relatively unhindered silyl cations, such as the triethylsilyl cation ... [Pg.123]
