Abstract

Tetraphenyl-phosphonium and -arsonium ions react with C5H5Fe(CO)2- to give 35-45% yields of PhFe(CO)2C5H5 and substantial amounts of dimer. Corresponding reactions of Re(CO)5- are much slower and yield only Re2(CO)10. Tetraphenylarsonium salts of less nucleophilic carbonyl anions including C5H5M(CO)???- (M = Mo, W), Mn(CO)5-, Co(CO)4- and V(CO)6- are isolable as crystalline solids and are stable at 25°C. Base sensitive quarternary ammonium ions, PhMe3N+ and PhCH2Me3N+, also react slowly with C5H5Fe(CO)2- to quantitatively yield CH3Fe(CO)2C5H5 and PhCH2Fe(CO)2C5H5, respectively. A comparison of the reactions of these organometallic bases and non-metallic bases such as hydroxide ion and carbanions with quarternary onium ions is presented.
