摘要：

Enhancement of NMR signals by para-hydrogen induced polarisation is shown to facilitate the detection of isomers of Ru(CO)(2)(H)(2)(PPh3)(2) and Ru(CO)(3)(H)(2)(PPh3) which contain inequivalent hydride ligands, and to demonstrate that Ru-3(CO)(9)(PPh3)(3) adds H-2 to form Ru-3(CO)(8)(H)(mu-H)(PPh3)(3), as well as undergoing fragmentation to form Ru(CO)(3)(H)(2)(PPh3).
