Abstract

Included is an invention, which in one aspect, is a process for preparing a product of an alkaline earth metal compound having at least one BVB-heteromoeity and by-product of an alkali metal substance comprising operating an electrochemical cell, said cell having PA0 (1) a sacrificial alkaline earth metal anode, PA0 (2) a liquid electrolyte, which contains a solvent that is generally inert and a solute that has at least a residual alkali metal moiety and an incorporatable BVB-heteromoiety therein, and PA0 (3) an alkali metal substance segregative cathode, under conditions whereby said product and by-product are prepared. Provided, among other products, are alkaline earth metal organoborates. For example, magnesium triethylpyrrolylborate can be prepared by employing a magnesium anode, a solution of lithium triethylpyrrolylborate in tetrahydrofuran and a cupric oxide and carbon containing cathode. Intercalating cathodes can provide electrical current output.
