Parahydrogen-induced polarization (PHIP) is a rapid and cost-effective hyperpolarization technique using transition metal-catalysed hydrogenation with parahydrogen. We examined rhodium catalysts and their kinetic studies, rarely considered in the research of current PHIP. It emerged that rhodium complexes with electron-donating bisphosphine ligands, with a dicyclohexylphosphino group, appear to be more effective than conventional rhodium catalysts.
仲氢诱导极化（PHIP）是一种快速且经济高效的超极化技术，它利用过渡金属催化仲氢进行氢化反应。我们研究了铑催化剂及其动力学，这在当前PHIP研究中很少被考虑。结果表明，带有给电子双膦配体且含有二环己基膦基的铑配合物似乎比传统铑催化剂更有效。
