Sodium hydridotrimethylboronate and its ether solvate. Study of hydridotrialkylboronates as reagents for the preparation of beryllium hydrides

Sodium hydridotrimethylborate is tetrameric in benzene solution and its etherate, (NaBMe 3H) 4OEt 2 probably also retains its solid state cubane arrangement in benzene solution. Reactions of NaBR 3H (R  Me, Et) in a variety of ratios with halo and organoberyllium compounds have been studied. Exchan...

Summary:Sodium hydridotrimethylborate is tetrameric in benzene solution and its etherate, (NaBMe 3H) 4OEt 2 probably also retains its solid state cubane arrangement in benzene solution. Reactions of NaBR 3H (R  Me, Et) in a variety of ratios with halo and organoberyllium compounds have been studied. Exchange between Et 2Be and NaBEt 3H does not occur to any appreciable extent beyond the EtBeH stage and reaction of equimolar EtBeCl and NaBEt 3H resulted in the formation of EtBeH, isolated as its trimethylamine complex. NaBR 3H and BeCl 2 in 1 1 in 2 1 and 4 1 ratios did not yield pure beryllium hydrides.
