Triphenylphosphine 에 HCl 수용액을 가해서 염을 만들고 전류가 흐르는지 측정

PPh3에 HCl을 가해서 합성하고자 하는데 너무 간단해서 합성 방법이 나오질 않습니다.

따라서 제법에 대해서 comment 해주실 분 있으신지요.

염을 만드는 이유는 물에 녹이기 위한 것이 있구요....

고체인 염 자체 또는 용매에 녹은 상태로 전류를 흐르게 하기 위함입니다.

Cl 음이온과 HPPh3 양이온으로 해리되어 전류가 흐르기를 기대하는데요

이게 과연 가능할까요 아니면 저의 미개한 생각 일까요?

    Triphenylphosphine in ether reacts with HI or HBr to form the solid triphenylphosphonium salts Ph3PHI and Ph3PHBr; with HCl the solid salt Ph3P · 2 HCl is formed. This salt consists of the ions [Ph3PH]⊕ and [HCl2]?; it is the first reported [HCl2]? salt of a phosphonium base. Ph3P · 2 HCl slowly decomposes into triphenylphosphine and hydrogen chloride; Ph3PHCl may be an unstable intermediate in this reaction, but no evidence was found for the existence of Ph3PHCl as a stable compound. The alleged compound Ph3P · 1.33 HCl1 is a mixture of Ph3P · 2 HCl and Ph3P. Triphenylphosphine reacts with HF to form liquid products consisting of Ph3PHF and Ph3P · 2 HF, the latter compound consisting of [Ph3PH]⊕ and [HF2]? ions. Very strong PH[BOND]X bonds are found in Ph3PHF; in Ph3PHBr and Ph3PHI the PH[BOND]X bonds are considerably less strong, while such bonds are absent in Ph3P · 2 HCl and Ph3P · 2HF. The differences between triphenylphosphine and triethylphosphine in their reactions with hydrogen halides (and water) can be explained by their difference in basicity.

    저도 HCl gas와 반응을 시켜면 될 것으로 생각은 했지만 근거 문헌을 가지고 있지 않아서 답글을 달지 않았는데 아주 명확한 참고문헌을 올려 주셨네요.
