SYNTHESIS OF LMH-2.
Abstract
High purity CBH was obtained by dissolution of the impure material in diethyl ether and filtration of the precipitated impurities, thereby permitting the use of low grade BeCl2. Techniques for rapid disproportionation of CBH with high conversion to BeH2 were developed. Disproportionation of CBH under vacuum gave BeH2 with purities of up to 88 wt.%; conversions of up to 87% based on initial CBH were obtained. Disproportionation of CBH in dimethyl sulfide gave BeH2 with purities of up to 90 wt.% with a conversion of 16% based on the initial CBH. Residual chloride and ether continued to contaminate the final product. LiAlH4 treatment of the final product reduced chloride and ether contaminants to tolerable levels, but hydrolytic impurities incorporated during handling lowered the purity. (Author)
