Summary
We synthesized novel amidomagnesium cations using tris{2-(dimethylamino)-ethyl}amine (Me6TREN). These cations exhibit unique reactivity with benzophenone, CO2, and water, offering insights into magnesium chemistry.
Area of Science:
- Organometallic Chemistry
- Main Group Chemistry
Background:
- Magnesium cations are crucial in catalysis and synthesis.
- Exploring novel ligand environments for magnesium is essential for understanding its reactivity.
Purpose of the Study:
- To synthesize and characterize novel amidomagnesium cations stabilized by the Me6TREN ligand.
- To investigate the reactivity of these cations with various electrophiles.
Main Methods:
- Synthesis of amidomagnesium cations using Me6TREN.
- Structural characterization using X-ray crystallography.
- Reactivity studies with benzophenone, CO2, and H2O.
Main Results:
- Isolation and structural determination of [Me6TREN-Mg-N(SiHMe2)2]+ and [Me6TREN-Mg-N(SiMe3)2]+.
- Observation of carbonyl insertion into a Si-H bond with benzophenone.
- Formation of silyloxy and hydroxide complexes upon reaction with CO2 and H2O, respectively.
- Failure to synthesize hydridomagnesium cations, yielding MgH2 and a potassium complex.
Conclusions:
- Me6TREN stabilizes magnesium cations in different coordination modes (κ4 and κ3).
- Amidomagnesium cations exhibit diverse reactivity, including insertion and hydrolysis reactions.
- The synthesis of hydridomagnesium cations via this route is not feasible.

00:57Cationic Chain-Growth Polymerization: Mechanism
2.9K
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the...

01:18Aromatic Hydrocarbon Cations: Structural Overview
3.8K
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

01:18π Molecular Orbitals of the Allyl Cation and Anion
5.5K
An allyl group is a three-carbon conjugated system where the sp³-hybridized allylic carbon is bonded to a CH=CH2 group via a single bond. Allyl anions can be obtained by treating propene with a strong base that can deprotonate methyl groups. Allyl cations are formed as intermediates during substitution reactions involving allylic halides. In both cases, the hybridization of the allylic carbon changes from sp3 to sp2, giving rise to a carbon chain with three sp2-hybridized carbons, each with...

03:46Qualitative Analysis
24.1K
For solutions containing mixtures of different cations, the identity of each cation can be determined by qualitative analysis. This technique involves a series of selective precipitations with different chemical reagents, each reaction producing a characteristic precipitate for a specific group of cations. Metal ions within a group are further separated by varying the pH, heating the mixture to redissolve a precipitate, or adding other reagents to form complex ions.

02:42Ionic Crystal Structures
17.0K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

03:34Ionic Compounds: Formulas and Nomenclature
86.9K
An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a nonmetal) to produce ions through complete electron transfer. The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.
