Silica-Grafted Tris(neopentyl)aluminum: A Monomeric Aluminum Solid Co-catalyst for Efficient Nickel-Catalyzed Ethene Dimerization

A silica-supported monomeric alkylaluminum co-catalyst was prepared via surface organometallic chemistry by contacting tris(neopentyl)aluminum and partially dehydroxylated silica. This system, fully characterized by solid-state 27Al NMR spectroscopy augmented by computational studies, efficiently activates (nBu3P)2NiCl2 towards dimerization of ethene, demonstrating comparable activity to previously reported dimeric diethylaluminum chloride supported on silica. Three types of aluminum surface species have been identified: monografted tetracoordinated Al species as well as two types of bisgrafted Al species—tetra- and pentacoordinated. Of them, only the monografted Al species is proposed to be able to activate the (nBu3P)2NiCl2 complex and generate the active cationic species.

Group 13-derived radicals from α-diimines: Via hydro-and carboalumination reactions

The mechanochemical synthesis of tertiary and secondary alanes AlR3 (R = Np 1 or Mes 2; HAlR2 R = Np 3 or Mes 4) is described. These species are reacted with several α-diimines to give a series of aluminium-derived radicals of the form [(diimine)AlR2] (6-11). EPR and several crystallographic studies are reported. These species are thought to form via hydro-or carboalumination and subsequent elimination reactions. This view is supported by the structural data for minor products C12H7(NHDipp)(NDipp)AliBu25 and C13H8(C(iBu)N(m-Xy)(NH(m-Xy)))AliBu212. In addition, the characterization of (C6F5)2B(OC(C6F5)OC12H8) indicates that such a carboboration pathway also provides access to related boron-derived radicals.

Synthesis and characterization of neopentylaluminum compounds

The series of neopentylaluminum compounds, Al(CH2CMe3)3, Al(CH2CMe3)2H, Al(CH2CMe3)2Br, (Me3CCH2)2AlPPh2, and (Me3CCH2)2AlN(Me)H, have been prepared by reactions typical in organoaluminum chemistry and characterized by elemental and/or group analysis, cryoscopic molecular weight measurements in benzene solution, and IR and NMR spectroscopic data. All compounds in this series, except Al(CH2CMe3)3, are associated in benzene solution. Even though the neopentyl group is considered a bulky ligand with significant eteric effects, the Lewis acidity of Al(CH2CMe3)3 has been established by the formation and characterization of adducts LiAl(CH2CMe3)4, (Me3CCH2)3Al·PPh2H, and (Me3CCH2)3Al·N(Me)H2. However, since Al(CH2CMe3)3 is monomeric in benzene solution, the factors influencing the degree of association of organoaluminum compounds are discussed. The crystalline hydride Al(CH2CMe3)2H has been prepared from Al(CH2CMe3)3 and LiAlH4. The other product was LiH rather than LiAl(CH2CMe3)H3. These observations of products are unusual in organoaluminum chemistry.

Novel trivalent organometallic compounds and methods of preparing same

In the manufacture of semiconductors it is desirable to make controlled deposits of certain phosphides or arsenides of trivalent metals such as gallium, indium and aluminum. There are provided novel neopentyl derivatives of these metals whose stability characteristics makes them ideally suited for the above purpose.
