[MnBrL(CO)4] (L = Amidinatogermylene): Reductive Dimerization, Carbonyl Substitution, and Hydrolysis Reactions

First reductive dimerization of a polycyclic azine.

The tptz molecule is reduced by potassium into its anion-radical in the compound K(tptz)(2) (), whereas it is reductively coupled by SmI(2) and UI(3)(py)(4) into the bis-triazinide ligand in the dinuclear complexes [Sm(2)(tptz-tptz)(DMF)(8)][I](4).3.5DMF (.3.5DMF) and U(2)I(6)(tptz-tptz)(MeCN)(2).2MeCN (.2MeCN) where each metal ion occupies a pentadentate N(5) cavity of the [tptz-tptz](2-) ligand.

Indenyl effect in dissociative reactions. Nucleophilic substitution in iron carbonyl complexes: a case study.

The mechanism of carbonyl substitution in [Fe(Ind)(CO)(2)I] (Ind = C(9)H(7)(-), indenyl) by P(OMe)(3) was investigated by means of DFT calculations. The most favourable path involves a spin crossover of the complex from the ground state singlet to the triplet potential energy surface (S = 1), followed by dissociative loss of CO, and phosphite addition to the coordinatively unsaturated intermedi...

Organocatalyzed Intramolecular Carbonyl-Ene Reactions.

An organocatalyzed intramolecular carbonyl-ene reaction was developed to produce carbocyclic and heterocyclic 5- and 6-membered rings from a citronellal-derived trifluoroketone and a variety of aldehydes. A phosphoramide derivative was found to promote the cyclization of the trifluoroketone, whereas a less acidic phosphoric acid proved to be a superior catalyst for the aldehyde substrates.

One-pot reductive Amination of Carbonyl Compounds using NaBH4 and Fe3O4 Magnetic Nanoparticles

One-pot reaction of aldehydes or ketons with aniline derivatives was performed using NaBH4 and Fe3O4 magnetic nanoparticles (MNPs). The optimum amount of Fe3O4 MNPs was 5 mol% under solvent free condition. The corresponding products were obtained in good to excellent yields. The magnetically recoverable iron oxide nanoparticles are found to be efficient for synthesis of amine derivatives. These...
