Fernandes, Tiago A.; Nunes, Carla D.; Vaz, Pedro D.; Calhorda, Maria José; Brandão, Paula; Rocha, João; Gonçalves, Isabel S.; Valente, Anabela A.

Reaction of [MnIII(acac)3] and [VIVO(acac)2] with the 1,4-diazabutadiene (DAB) ligands Ph-DAB-(CH2)3R [R = Si(OEt)3(1a); H (1b)] (L) leads to complexes of the type [MnII(acac)2L] and [VIVO(acac)L]Cl in good yields. These complexes were characterised by spectroscopic techniques, and magnetic measurements showed that in the case of the manganese the metal was reduced during the reaction with the nitrogen ligand. ...


Complex Formation between Heptakis(2,6-di-O-methyl)-β-cyclodextrin and Cyclopen...

Pereira, Cláudia C. L.; Diogo, Cátia V.; Burgeiro, Ana; Oliveira, Paulo J.; Marques, Maria Paula M.; Braga, Susana S.; Paz, Filipe A. Almeida

The inclusion compounds isolated from nonaqueous solutions of heptakis(2,6-di-O-methyl)-β-cyclodextrin (DIMEB) and the complexes [CpMoL2(CO)2](BF4) (L = MeCN, L2 = 2,2′-biimidazole) were characterized in the solid state by powder X-ray diffraction (XRD), thermogravimetric analysis (TGA), 13C1H CP/MAS NMR, and FTIR spectroscopy. Powder XRD showed that the compound with [CpMo(MeCN)2(CO)2](BF4) was amorphous, whil...


Dichloro and dimethyl dioxomolybdenum(VI)–diazabutadiene complexes as catalysts...

Moreira, José A.; Valente, Anabela A.; Pillinger, Martyn; Nunes, Carla D.; Gonçalves, Isabel S.; Lopes, André D.; Romão, Carlos C.; Kuhn, Fritz E.

The dioxomolybdenum(VI) complex [MoO2Cl2{p-tolyl(CH3DAB)}] has been prepared in good yield by reaction of the solvent adduct MoO2Cl2(THF)2 with one equivalent of the bidentate ligand N,N-p-tolyl-2,3-dimethyl- 1,4-diazabutadiene. Treatment of the dichloro complex with the Grignard reagent CH3MgCl gives the dimethyl derivative [MoO2(CH3)2{p-tolyl(CH3DAB)}]. The complexes are highly active and selective catalysts ...

Lima, Sérgio; Gonçalves, Isabel S.; Ribeiro-Claro, Paulo; Pillinger, Martyn; Lopes, André D.; Ferreira, Paula; Teixeira-Dias, José J. C.; Rocha, João

The inclusion compounds formed between β-cyclodextrin (β-CD) and the tetrafluoroborate salts [Cp‘Mo(η4-C6H8)(CO)2][BF4] and the neutral derivatives Cp‘Mo(η3-C6H7)(CO)2 [Cp‘ = Cp (η5-C5H5), Ind (η5-C9H7)] were studied by means of elemental analysis, FTIR spectroscopy, thermogravimetric analysis (TGA), powder X-ray diffraction (XRD), and magic-angle spinning (MAS) NMR (13C, 11B). Additional information concerning...
