Abstract

Abstract : A simple and almost quantitative synthesis of the first salts of the PCO − anion with organic cations is presented. Moreover, we discovered a simple synthesis for [P( n Bu)3 Me] + 3 [Sb11 ] 3−, the first organic cation salt comprising the Zintl-anion [Sb11 ] 3− . Abstract : Herein we report the synthesis of the first ionic liquids with the highly reactive and synthetically valuable phosphaethynolate (PCO − ) anion. They are simply synthesised by the reaction of organic methylcarbonate salts with P(SiMe3 )3 . The products are obtained in near to quantitative yields and they are highly viscous liquids at room temperature or have low melting points for symmetric cations. Moreover, extending this synthetic strategy towards Sb(SiMe3 )3 we discovered a simple synthesis for [P( n Bu)3 Me] + 3 [Sb11 ] 3−, the first organic cation salt comprising the Zintl-anion [Sb11 ] 3− .
