- Reaction of Trialkylboranes with Sodium Diethylhydroaluminate in the Presence of 1,4-Diazabicylooctane: a Convenient, General Method for Preparation of Sodium Trialkylhydroborates
-
Trialkylboranes in tetrahydrofuran solution, even those with exceptionally large steric requirements, react readily with toluene solutions of sodium diethyldihydroaluminate in the presence of 1,4-diazabicyclooctane, resulting in a convenient and general preparation of sodium trialkylhydroborates.

- Method for producing alkali metal monohydridoborates and monohydridoaluminates
-
The invention relates to a method for producing compounds of general formula (A) by reacting an alkali metal hydride with a compound (B) during which the reaction is carried out in the presence of a catalyst that contains boron, whereby: M represents Li, Na, K, Rb or Cs; E represents B or Al, and; X1, X2, X3, independent of one another, represent a secondary or tertiary alkyl group, which is comprised of 2 to 10 atoms, or represent a phenyl group which itself can be alkyl-substituted or they represent an alkoxy group, and the catalyst, which contains boron, or the conversion product thereof with MH is capable of acting as a hydride transfer agent.

- Method of synthesis of alkali metal trisubstituted borohydride reagents
-
Synthetic routes for forming alkali metal substituted borohydride compounds include the step of reacting an alkali metal reagent, a hydrogen donor, and a substituted borane. The reactions proceed without the requirement of specialized handling of alkali metal hydrides associated with prior synthetic processes for the production of alkali metal trisubstituted borohydride compounds. A chemical composition comprises solid potassium tri-sec-butyl borohydride.
