(Pentamethylcyclopentadienyl)molybdenum Bromides and Iodides

Inorganic Chemistry, 1994
Contrary to the (pentamethylcyclopentadienyl)trichloromolybdenum(IV) system, for which the molecular [Cp{sup *}MoCl{sub 2{minus}}({mu}-Cl)]{sub 2} complex is the only form observed, the corresponding chemistry of the heavier halide systems is much more complex.

Pentamethylcyclopentadienyl imido compounds of chromium

Journal of the Chemical Society, Dalton Transactions, 1996
The interaction of the pentamethylcyclopentadienylchromium(III) complex [CrBr(µ-Br)(η-C5Me5)]2 with alkyl- and aryl-lithium amido compounds, LiNHR, gave products whose nature depends on the reactants and on reaction conditions. For the aryl (R) 2,6-Pri2C6H3 both [(η-C5Me5)Cr(µ-NR)(µ-NHR)(µ-Br)Cr(η-C5Me5)]1 and [Cr(η-C5Me5)(µ-NR)]22 were obtained ...

Amidobis(pentamethylcyclopentadienyl)titanium(III)

Acta Crystallographica Section C Crystal Structure Communications, 1995
The title compound, [Ti(NH 2 )(Me 5 C 5 ) 2 ] (I), is a bent metallocene with the NH 2 group oriented so as to maximize the π interaction between the N and Ti atoms.

Pentamethylcyclopentadienyl-rhodium and -iridium complexes

Journal of Organometallic Chemistry, 1975
Abstract The synthesis of the novel di-μ-hydridoiridium complexes [H 2 (IrC 5 Me 5 ) 2 X 2 ] (X = Br, Cl) is described. These complexes react with butadiene, but only in very polar solvents, to give η-1-methylallyl complexes, with phosphines to give [HIrC 5 Me 5 (X)(R 3 P)], and with AgOCOR to give [H 2 (IrC 5 Me 5 ) 2 OCOR] + .

Bis(η5-pentamethylcyclopentadienyl)-and(η5cyclopentadienyl) (η5-pentamethylcyclopentadienyl)-platinium dications: Pt(IV) metallocenes

Journal of Organometallic Chemistry, 1994
Abstract Reaction of [Pt2(η5-C5Me5)2(η-Br)3]3+(Br−)3 with C5R5H (R = H,Me) in the presence of AgBF4 gives the first platinocenium dications, [Pt(η5-C5Me5)(η5-C5R5)]2+(BF4− )2. On electrochemical reduction, [pt(η5-C5Me5)2]2+ yields [Pt(η4-C5Me5H)(η2-C5Me5)]+ BF4−.

Ammonolysis of Mono(pentamethylcyclopentadienyl) Titanium(IV) Derivatives

Inorganic Chemistry, 2000
Ammonolyses of mono(pentamethylcyclopentadienyl) titanium(IV) derivatives [Ti(eta5-C5Me5)X3] (X = NMe2, Me, Cl) have been carried out in solution to give polynuclear nitrido complexes. Reaction of the tris(dimethylamido) derivative [Ti(eta5-C5Me5)(NMe2)3] with excess of ammonia at 80-100 degrees C gives the cubane complex [[Ti(eta5-C5Me5)]4(mu3-N)4] (1)

Pentamethylcyclopentadienyl Aminoborole Complexes of Hafnium

1997
The tricyclophosphate ligand, (P₃O₉)³⁻, was investigated as an oxidation resistant ligand for ruthenium chemistry. The silver salt of tricyclophosphate, Ag₃(P₃O₉).H₂O, was found to be a useful synthon in the preparation of organic soluble tricyclophosphate salts. The complex [(P₃O₉)Ru(C₆H₆)]⁻ was prepared and characterized.

Preparation of pentamethylcyclopentadienyl-dialkylnitrosyliron complexes

Journal of Organometallic Chemistry, 1985
Abstract The dimer [(CH 3 ) 5 C 5 Fe(NO)] 2 has been prepared by octane reflux of [(CH 3 ) 5 C 5 Fe(CO) 2 ] 2 under a NO atmosphere. Oxidative cleavage of the dimer with iodine yields (CH 3 ) 5 C 5 Fe(NO)I 2 . Alkylation with two equivalents of RLi or RMgX (R = CH 3 , CH 2 C 6 H 5 , or CH 2 SC 6 H 5 ) leads to the dialkyl derivatives in good ...
