Abstract

Diborane is prepared by reacting lithium hydride with a boron halide in the presence of tetrahydrofuran, while maintaining the reaction mixture at substantially reflux temperatures during at least the first part of the reaction period. The boron halide may be the fluoride or chloride, as such, or may be dissolved in tetrahydrofuran as the tetrahydrofuranate. The halide is added slowly to a slurry of lithium hydride in tetrahydrofuran in a vessel equipped with a reflux condenser. The mixture is refluxed by external heating at least during the addition of the first 3/4 boron halide. The reflux may be continued after the boron halide addition. If a saturated solution of diborane in tetrahydrofuran is required the temperature is lowered during the addition of the last part of the boron halide, or all, or part of the final reflux is eliminated, and the lithium halide is separated by filtration.
