The chemistry of the ligand (R2PCH2SiMe2)2N− (R=cyclohexyl and tBu), “PNP-R”, on ruthenium is developed, including RuH(PNP-Cy)(PPh3) and (HPNP-R)RuH3Cl. The latter contains a protonated nitrogen (i.e., amine as a donor to Ru) and one H2 ligand (X-ray structure for R=tBu). This compound can be dehydrohalogenated to give (PNP-Cy)RuH3, which undergoes H/D exchange of D2 into its cyclohexyl rings, and
配位体的化学性质(R 2 PCH 2森达2)2 ñ - (R =环己基和吨丁基),“PNP-R”,钌被显影,包括期RuH(PNP-CY)(PPH 3)和(HPNP -R)RuH 3 Cl。后者包含质子化的氮(即,胺作为Ru的供体)和一个H 2配体(R = t Bu的X射线结构)。该化合物可以脱卤化氢得到(PNP-Cy)RuH 3,其经过D 2的H / D交换进入其环己基环,并且本身被过量的H 2 C脱氢CHR得到[Cy 2 PCH 2 SiMe 2 NSiMe 2 CH 2 PCy(C 6 H 8)] Ru,该Ru包含与Ru结合的三脱氢环己基环π-烯丙基。(PNP-Cy)RuH 3与二氢呋喃反应,得到杂原子稳定的卡宾配合物(PNP-Cy)RuH [ CO(CH 2)3 ]。
