Pentanuclear clusters, substitution

Publications on pentanuclear clusters include reports on the substitution chemistry, reactivity towards allyl halides, and high temperature thermolysis of [Ru,(CX>) ((X-PPhi)( i -Cy Ph2)], the latter giving the isomer [Rus(CO) ([i-PPh2)(M. -HTi)(li -C2Ph)], a result... [Pg.158]

Heating of 247 with ethylene in hexane afforded, in addition to 249, the pentanuclear cluster [Ru4lr(/i-H)-(/i4-GGH3)(GO)is], in which the ethylidyne ligand is in a rarely observed / 4-coordination mode. Site-selective substitutions with phosphine, phosphite, and related ligands on 246 and 248 have been observed. [Pg.1092]

There are two examples of alkyne-substituted clusters in which there is an interaction between the alkyne and five-metal centers. Both occurrences are found in the related pentanuclear ruthenium complexes Ru5(CO)14(/i-PPh2)(C=CPh) (431) and Ru5(CO)12(p-... [Pg.223]
