RESEARCH ON ORGANOALUMINUM COMPOUNDS
Abstract
The synthesis and reactions of a variety of organic Al compounds were investigated. The reactions of primary, secondary, and tertiary amines with (C2H5)3Al and (C2H5)2AlH were studied, and the thermolysis of several of the resulting Al-N, compounds was examined. (C2H5)2AlN3 and (C2H5)2Al(C6H5) were prepared from (C2H5)2AlCl and the corresponding metal salts. Attempts to obtain di-al compounds and cyclic Al compounds from ethylaluminum chlorides and bifunctional metal alkyls produced (C2H5)3Al and Al-containing polymers. The same products were obtained in the attempted preparation of di-al compounds from alkynes and (C2H5)2AlH. Al-C bond containing products were obtained from the reactions of terminal dihaloalkanes with Al, and with Al-Mg alloy. Carbene (CH2!) was not produced in the reaction of CH2I2 with Al. Al alkyls and related organoaluminum compounds were readily oxidized by cobaltous chloride and some other metal halides. The products of these reactions were alkanes, alkenes, Al halides, and metal from the oxidizing agent. A precision, quasi-adiabatic calorimeter was constructed for the measurement of the heats of coordination or organoaluminum compounds with electron donors. Al aryls required for these determinations were prepared by modified classical procedures. (Author)
