While the chemistry of phosphenium compounds, including metal complexes thereof, is very well established, few derivatives having a P-H bond have been described, yet. This work describes rational access to donor-stabilised phosphenium metal complexes possessing a P-H bond using protonation reactions of stable phosphinidene complex adducts. While most Brønsted-Lowry acids yield formal 1,1-addition products at the phosphorus centre under the loss of the donor, super-strong acids having weakly coordinating anions enable access to donor-stabilised P-H phosphenium complex salts. The latter possess -methylimidazole as a donor (to phosphorus) and the N-P interaction has been studied theoretically.
虽然磷鎓化合物（包括其金属配合物）的化学性质已得到充分确立，但迄今为止，具有P-H键的衍生物却鲜有报道。这项工作描述了通过稳定的磷烯配合物加合物的质子化反应，合理地获得具有P-H键的给体稳定型磷鎓金属配合物。虽然大多数布朗斯特-劳里酸在失去给体的情况下会在磷中心生成形式上的1,1-加成产物，但具有弱配位阴离子的超强酸能够制得给体稳定型P-H磷鎓配合物盐。后者以-甲基咪唑作为给体（与磷配位），并且已对N-P相互作用进行了理论研究。
