LiBH

Thallium(1) salts of tetrahydridoborate and aluminate are obtained from a T1(I) compound, eg, ethoxide, perchlorate, or nitrate, and LiBH or LiAlH ia ether. ThaIlium(I) tetrahydridoborate [61204-71 -5] TIBH, is unstable at 40°C, evolving diborane. Thallium(I) tetrahydridoaluminate... [Pg.469]

This method has been used for the commercial production of NaBH, but is less satisfactory for the manufacture of LiBH and KBH. Some metathetical conversions are shown ia equations 53—58. [Pg.239]

Other tetrahydroborates of less commercial importance are lithium borobydride [16949-15-8], LiBH, and potassium borobydride [13762-51 -1],... [Pg.259]

Reduction with Metals and Metal Hydrides. Practically any ester can be reduced by Na—C2H OH, Li or Na—NH, LiAlH, LiBH, or NaBH to give alcohols in excellent yield (35,36). Carbon-carbon double bonds are usually preserved using these reducing reagents. [Pg.389]

Diastereoselective synthesis of lactones.1 Acylation of the enolate (LDA) of the vinylogous urethane (1) results in a product (2) that on reduction with LiBH[CH(CH3)C2H5]3 (3) forms the anft-lactone (4) exclusively (equation I). This two-step synthesis of lactones is the equilvalent of an aldol condensation between... [Pg.195]

Schlesinger and Brown synthesized the lithiumtetrahydroboride (lithiumbo-rohydride) (LiBH.,) by the reaction of ethyllithium with diborane (B HJ in 1940 (Schlesinger and Brown, 1940). It was the first report of a pure alkali metal tetrahy-droboride. The direct reaction of the corresponding metal with diborane in ethereal solvents under suitable conditions produces high yields of the tetrahydroborides (Huhey, 1978) ... [Pg.144]

Metal borohydrides are very well known chemicals and some of them have been used commercially in chemical industry for a number of years. The first metal borohydride, LiBH, was synthesized almost 70 years ago by the reaction of ethyl... [Pg.240]

LiBH undergoes first a polymorphic transformation around 110°C, then melts with an endothermic peak centered around 280°C, and evenmaUy at the atmospheric pressure it decomposes with an endothermic peak centered at 470°C through the following reaction path... [Pg.243]
