Abstract:
A distinctive synthetic route has been demonstrated in which the aminotroponiminato (ATI)-stabilized aluminum dihydride complex [(ATI)AlH2] was prepared from a [(ATI)SiHCl2] precursor. [(ATI)AlH2] was also isolated from aluminum(III) dichloride [(ATI)AlCl2] via salt-metathesis reaction. Subsequent reaction with the ATIH ligand enabled the isolation of the N-tetracoordinated (ATI)Al(III)-complex via aluminum monohydride [(ATI)AlH(ATI)] intermediate. The dihydride compound was found to activate CS (in CS2) and PSe (in Ph3PSe) bonds yielding the aluminum(III) μ-sulphide and μ-selenide dimer [(ATI)Al(μ-S)]2 and [(ATI)Al(μ-Se)]2, respectively. All compounds were characterized using multinuclear NMR spectroscopy and single-crystal X-ray diffraction.

E1 Reaction: Kinetics and Mechanism
Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
Esters to Alcohols: Hydride Reductions
Lithium aluminum hydride is a source of hydride ions and functions as a nucleophile. The mechanism proceeds in three steps. Firstly, the nucleophilic hydride ion attacks the carbonyl carbon of the ester to form a tetrahedral intermediate. Subsequently, the carbonyl group re-forms,...

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
Acid Halides to Alcohols: Grignard Reaction
Grignard reagents are a source of carbanions and function as nucleophiles. The mechanism begins with the nucleophilic attack by the carbanion at the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs,...
Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation reactions,...
