Usage

General Description

Trineopentylaluminium is a chemical compound primarily used as a catalyst in polymerization reactions, particularly in the production of polyethylene and polypropylene plastics. It belongs to the class of organoaluminum compounds and is a colorless, flammable liquid with a strong, pungent odor. Trineopentylaluminium is highly reactive and can undergo reactions with various organic compounds, making it an important component in the field of chemical synthesis. However, it is also known to be highly toxic and should be handled with extreme caution. Proper safety measures must be observed when working with trineopentylaluminium to prevent potential health hazards.

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.

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.
