Guidance literature:

In tetrahydrofuran; byproducts: LiBr; (Ar atm.) a THF soln. of Li-compound was added to a THF soln. of dibromogermane at -78°C, stirred for 1 h, tetrabromobenzene powder was added at -40°C; the solvent was removed in vac., extd. with hexane, filtered, the residue was subjected to GPLC (toluene) followed by gel premeation optical resolution chromy. using hexane as eluent, then wet column chromy.
