PROCESS FOR PRODUCING OLYGOMERE N-ALKYL-IMINO-ALANES OF REGULAR THREEDIMENSIONAL STRUCTURE PRODUCED FROM FOUR-MEMBER OR FOUR AND SIX-MEMBER RINGS

摘要

An oligomer N-alkyl-iminoalane, made up of a plurality of four and/or six member rings of the formulae: IMAGE wherein R is an aliphatic, cycloaliphatic or aromatic hydrocarbon combined in a tridimensional cage structure having the chemical composition (HAl-NR)n, in which R has the above meaning and n is a whole number lower than or equal to 10, is prepared by reacting a primary amine containing a secondary or tertiary carbon atom in alpha or beta position with respect to the amine nitrogen atom or amide derivative thereof wherein the amine radical contains a secondary or tertiary carbon atom in alpha or beta position with respect to the nitrogen atom with a complex formed by AlH3 and a Lewis base, or by reacting said primary amine with an alkali or alkaline-earth metal alanate.
