Alkali–metal dialkylberyllium hydrides and their thermal decomposition

G. E. Coates  and  R. E. Pendlebury  

Abstract

The complex hydrides, NaR2BeH (R = Prn, Pri, and Bui) are described, together with Li(OEt2)Bui2BeH, LiBui2-BeH, Na(OEt2)4But4Be2H, and Na(OMe2)Et2BeH. Pyrolysis of the isopropyl and of the butyl salts in the range 60–200° results in elimination of olefin and of some dialkyl, R2Be, to leave a residue of sodium beryllium hydrides the composition of which depends on the pyrolysis conditions.

Sodium di-isobutylberyllium hydride, which is insoluble in hydrocarbons, dissolves in solutions of di-isobutylberyllium in hexane up to a limit corresponding to the composition Na2Bui6Be3H2. Sodium diethylberyllium hydride combines with diethylberyllium to give a product, NaEt6Be3H, which is insoluble in hexane. Pyrolysis of this salt gives NaEt2BeH.

Di-isobutylberyllium may conveniently be characterized as its bispyridine adduct.
