Методика

Tricyclohexylphosphine is reacted with fluoroboric acid to synthesize tricyclohexylphosphonium tetrafluoroborate, which is reacted with sodium tetraphenylborate to produce tricyclohexylphosphonium tetraphenylborate (75% yield). A similar process is described in which tri-tert-butylphosphine is used as starting material to produce tri-tert-butylphosphonium tetraphenylborate (71% yield) (see Nonpatent Document 4).
