Cyclometalated Platinum(II) hydrides with nitrogen ligands / Zucca, Antonio; Stoccoro, Sergio; Cinellu, Maria Agostina; Petretto, Giacomo Luigi; Minghetti, G.. - In: ORGANOMETALLICS. - ISSN 0276-7333. - 26:23(2007), pp. 3.5621-3.5626. [10.1021/om7005276]
Abstract:
Platinum(II) (N-N-C) cyclometalated hydrides, [Pt(N-N-C)H], (N-N-CH ) 6-R-2,2¢-bipyridine,
R ) benzyl, phenyl, alkyl) have been obtained by reaction of the corresponding chlorides with NaBH4.
Alternatively, some of them can also be synthesized from formato derivatives [Pt(N-N-C)(OC(O)H]
by loss of CO2 or from cationic carbonyl species, [Pt(N-N-C)(CO)]+, by reaction with NaBH4. 1H
NMR characterization reveals 1J(Pt-H) values among the largest ever reported, ca. 1600 Hz. Dinuclear
derivatives with a bridging hydride, [(N-N-C)Pt(í-H)Pt(N-N-C)]+, both symmetric and unsymmetric,
can be built up through a classical approach, i.e., by reaction of a mononuclear terminal hydride and a
solvento cationic complex [Pt(N-N-C)(S)]+.
