摘要：
The invention relates to a process for the preparation of onium salts with dialkylphosphate, dialkylphosphinate or (O-alkyl)alkyl- or alkylphosphonate anions by reaction of an onium halide with a triallyl phosphate, alkyl dialkylphosphinate, dialkyl alkylphosphonate or trialkylsilyl ester or mixed alkyl trialkylsilyl ester of phosphoric, dialkylphosphinic or alkylphosphonic acid.
