Kinetic studies on the oxidation of hexa-aquamolybdenum(III) with [IrCl₆]^2–, [Co(C₂O₄)3]^3–, and aquavanadium(IV)

Carbon acidity. 70. Equilibrium ion pair acidities in tetrahydrofuran of benzylic carbon acids stabilized by an adjacent cyano, carboalkoxy, and sulfonyl substituent. Delocalization and aggregation of ion pairs

“…solutions.3,6 Note particularly that the lithium salts of phenyl-acetonitrile7 and benzyl phenyl sulfone8 are dimeric in the crystal state. The present results provide a useful demonstration that the structures of organolithium compounds in solution are not necessarily the same as structures in the crystal (7). Boche, V. G.; Marsch, M.; Harms, K. Angew.Chem.…”

Kinetics of the Interconversion of Parahydrogen and Orthohydrogen Catalyzed by Paramagnetic Complex Ions

“…Ni(OTf) 2 was recrystallized from 1 mM HOTf/D 2 O solution and dried under Ar stream to obtain Ni(OTf) 2 ·6D 2 O. V(BF 4 ) 2 ·6H 2 O, VO(OTf) 2 ·10H 2 O, Cr(OTf) 2 ·13H 2 O, [Co(phen) 3 ](ClO 4 ) 2 ·3H 2 O, [Cr(NCCD 3 ) 6 ](OTf) 3 , [Cr(bpy) 3 ](ClO 4 ) 3 , and [Cu(cyclam)](OTf) 2 were synthesized according to the literature methods.…”

Protons on a cluster surface. Reversible generation of agostic (carbon-hydrogen-metal) hydrogens from iron hydrides (iron-hydrogen-iron) on a saturated triiron cluster

“…radical ion pair states in a manner analogous to photosynthesis.17 formed by respective cluster deprotonation.4 The structures of I and II can be contrasted with those of the isoelectronic hydrocarbyl complexes Ilia and IVa. 5 The mobility of the hydrogens (1) See, for example: Grimes, R. N. In "Metal Interactions with Boron Clusters"; Grimes, R. N., Ed. ; Plenum Press: New York, 1982; p 269.…”

“…Cluster rearrangements in trimetal systems that require an intermediate or transition state similar to structure V have been (5) The ethylidyne derivative Illb has been fully described. Wong, K. S.; Fehlner, T. P. J.…”
