Pd(bcope)(OTf)2 (where bcope is (C8H14)PCH2CH2P(C8H14)) is shown to react with an alkyne in the presence of parahydrogen to form alkyl hydrides, such as Pd(bcope)(CHPhCH2Ph)(H), that are detectable by NMR spectroscopy because the proton resonances of the alkyl arm appear with strongly enhanced signal strengths.
二（环辛基膦）钯（II）双（三氟甲磺酸盐）（其中环辛基膦为（C8H14）PCH2CH2P（C8H14））在仲氢存在下与炔烃反应生成烷基氢化物，如Pd（环辛基膦）（CHPhCH2Ph）（H），通过核磁共振光谱可检测到这些烷基氢化物，因为烷基臂的质子共振信号强度显著增强。
