Alkalimetal Trialkylhydroxyborates and (Alkalimetaloxy)dialkylboranes

Et3B (1) and 9-Et-9-BBN (2) react with alkalimetal hydroxides (LiOH, NaOH, KOH) to yield the alkalimetal hydroxytriorganoborates M-3 and M-4, resp.Heating (about 100 deg C) of the borates, catalyzed by NaHBEt3, leads to elimination of ethane with formation of the boranes MOBEt2 (M-5, M = Na, K) or MOBC8H14 (M-7, M = Li, Na, K), which associate to compounds with BOB, BOM, or MOM bridge bonds.At temperatures higher than 160 deg C (without catalyst), M-3 (M = Li, Na) and Li-4 dissociate.Na-4 is dehydroborated with formation of H2 and NaOB(Et)C8H13 (Na-9).From K-7 and ClSiMe3 9-Me3SiO-9-BBN (10) is obtained.Na-9 reacts with ClSiMe3 to give a mixture of the unsaturated mixed borane 11 and the mixed diboroxane 12.The degree of the association of the alkalimetal compounds were determined by the specific electric conductivity measurements (κ) and by 17O-NMR spectroscopy.Key Words: Borates, trialkyl-, hydroxy- / Alkalimetal hydroxides / BC protolysis, BH-borate catalysis / Boranes, (alkalimethaloxy)dialkyl- / Dimers with BOB bonds, MOM bonds / 1,3,2-Diboroxanes, organosubstituted
