in tetrahydrofuran byproducts: THF; under N2, THF soln. of 1 equiv. of LiOBut in THF was added to 0.064 M soln. of BH3*THF in THF at -78 °C, warming to room temp.; the same result was obtained with mixing at room temp.; monitored by (11)B NMR; LiBH2(OBut)2 and LiB(OBut)4 were not formed;

in tetrahydrofuran byproducts: Na-phthalate; under N2, B-compd. in THF was added to THF soln. of Na-compd., solvent was removed, extd. with hexane and Et2O; using 3 equiv. of solid alkali-compd. gave reproducible result; monitored by (11)B NMR; hexane phase was crystd. for 2 weeks at -80 °C which lead to the solvated compd., Et2O contained NaB(OtBu)4, the hexane phase contained HB(OtBu)2 and B(OtBu)3;
