The aza-Henry reaction is an efficient route to important chiral, vicinal diamines. Reports of the asymmetric version typically use electron-deficient acyclic imines. We report the first example of a catalytic, asymmetric aza-Henry reaction on an unfunctionalized cyclic imine that gives access to enantiopure diamine derivatives under experimentally straightforward conditions. The stereocentre is established through the initial nitromethane addition to the imine. The scalemic intermediate may be trapped through acylation, then crystallized. Copyright

Asymmetric bromine-lithium exchange: On the importance of both the diamine ligand and the organolithium reagent

The asymmetric bromine-lithium exchange on a series of prochiral biphenyls was investigated. As in many asymmetric organolithium reactions, the chiral ligand (here a diamine) was considered to be the enantiocontrolling element. We show here that the organolithium reagent also plays an important role.

Facile cleavage of Si-C bonds during the sol-gel hydrolysis of aminomethyltrialkoxysilanes – A new method for the methylation of primary amines

The reaction of chloromethyltriethoxysilane with (1R,2R)-bis(methylamino) cyclohexane (1) afforded the corresponding bis-silylated compound 2. The sol-gel hydrolysis of 2 did not give the expected bridged silsesquioxane owing to quantitative Si-C-bond cleavage. Instead, silica and (1R,2R)-bis(dimethylamino) cyclohexane (3) were obtained. This reaction was exploited to propose a new route for the methylation of amines. Such methylation reaction of amines could be extended to other amines and provides a new method for the selective monomethylation of primary amines. Wiley-VCH Verlag GmbH & Co.

On the specific rotation of deuterium-containing isotopomers of 2-dimethylaminocyclohexyl-1-trimethylammonium iodide

The specific rotation of a variety of differential isotopomers is reported. The difference in their specific rotation appears to be greater than their percentage mass difference and each isotopomer seems to rotate (the plane of) plane-polarized light differently. Copyright

Optical and magneto-optical properties of spin coated films of novel trinuclear bis(oxamato) and bis(oxamidato) type complexes

This work reports the first example of the spectroscopic measurements of the Magneto-Optical Kerr Effect (MOKE) of films being composed of trinuclear transition metal complexes on a non-transparent substrate at room temperature. The thin films of the tailor-made trinuclear bis(oxamidato) type complex 5 ([Cu3(opbonPr2)(tmcd)2(NO3)2], opbonPr2 = o-phenylenebis(N’-npropyloxamido, tmcd=trans-(1 R,2 R)-N,N,N?,N?-tetramethyl-cyclohexanediamine) and of the bis(oxamato) type complexes 11 ([Cu2Ni(opbaCF3)(pmdta)2(NO3)2], opbaCF3 = 4-trifluoromethyl-o-phenylenebis(oxamato), pmdta = N,N,N,?N?,N?-pentamethyldiethylenetriamine) and 12 ([Cu3(opba)(bppe)2(NO3)2] (opba = o-phenylenebis(oxamato), bppe = S-N,N-bis(2-picolyl)-1-phenylethylamine) were fabricated by spin-coating and their thicknesses in the range between 0.5 mum and 2 mum was determined by spectroscopic ellipsometry. Based on the spectroscopic ellipsometry results it was also possible to determine the optical constants of the film and compare them with the absorption of the complexes in solution in order to confirm the complex integrity after the film deposition. The fabrication of high-quality films which exhibit Kerr rotation up to 0.2 mrad (11.5 mdeg) was only possible due to tailor-made synthesis, which allows circumventing intermolecular interactions of the trinuclear complexes during the film formation.

Structure of n-butyllithium in mixtures of ethers and diamines: Influence of mixed solvation on 1,2-additions to imines

n-BuLi in diamine/dialkyl ether mixtures forms ensembles of hetero- and homosolvated dimers. Solutions in TMEDA/THF (TMEDA = N,N,N?,N?- tetramethylethylenediamine) are not amenable to detailed investigation because of rapid ligand exchange. TMCDA/THF mixtures (TMCDA = trans-N,N,N?, N?-tetramethylcyclohexanediamine) afford clean assignments for a mixture of homo- and heterosolvated dimers but demonstrate poor control over structure. TMCDA/tetrahydropyran (THP) mixtures and TMEDA/Et2O mixtures afford clean structural assignments as well as excellent structural control. Rate studies of the 1,2-addition of n-BuLi using TMCDA/THP mixtures reveal cooperative solvation in which both THP and TMCDA coordinate to lithium at the monomer- and dimer-based transition structures. The two mechanisms are affiliated with markedly different stereochemistries of the 1,2-addition to imines. The results show strong parallels with previous investigations of 1,2-additions in TMEDA/Et2O mixtures.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Computed Properties of C10H22N2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 53152-69-5, in my other articles.

The smaller, the better? How the aggregate size affects the reactivity of (trimethylsilyl)methyllithium

Weighting both the basicity and nucleophilicity of an organolithium compound is crucial for an effective use of these reagents in syntheses. To achieve this, an aggregate of optimal size and reactivity has to be formed by adding suitable donating agents. Against usual expectations, this is not inevitably the smallest possible aggregate. In this work, we show that the monomeric complex of (trimethylsilyl)methyllithium stabilized by the bidentate ligand (R,R)-TMCDA shows no significant reactivity. In contrast, two dimeric aggregates stabilized by monodentate quinuclidine were obtained, exhibiting enhanced reactivity compared to the parent compound and to the monomeric complex.
