Cyclopentadiene Elimination Reaction as a Route to Bis(Neopentyl)Gallium Phosphides, Crystal and Molecular Structures of (Me3CCh2)2GaPEt22 and (Me3CCH2)2GaP(C6H11)22.
Abstract
A major challenge for synthetic group 13 chemistry is to discover new reactions for the preparation of ultrapure precursors for electronic materials. Thus, the simplest and most direct route which involves the most limited number of synthetic steps from the fewest reagents of high purity at the lowest possible reaction temperature should minimize the introduction of impurities. Consequently, our research has been directed toward the use of the hydrocarbon elimination reaction and the search for novel examples which occur at or below room temperature. The cyclopentadiene elimination reaction between R2Ga(C5H5)(R=Me2, Et3) and either amines, phosphines or thiols is an example of an elimination reaction which typically occurs at or below room temperature. Our studies of these reactions, suggested that the association of the initial group 13-15 monomeric product and/or removal of the cyclopentadiene monomer by either dimerization or distillation was necessary to minimize the occurrence of the back-reaction.
