摘要：

Dimethyl-, diethyl-, and diphenylberyllium were found to redistribute rapidly with BeCl2 and BeBr2 in diethyl ether contrary to earlier reports. The redistribution was determined by a combination of selective precipitation, molecular association, and low-temperature nmr techniques. The composition of a mixture of R2Be + Be-X2 in diethyl ether solution is represented by the equilibrium R2Be + BeX2 * RBeX. This equilibrium lies predominantly if not entirely to the right for the compounds studied. The reasons for earlier work indicating no exchange results appear to have been found. © 1968, American Chemical Society. All rights reserved.
