Stabilized tetrahydrofuran solutions of diborane
Abstract
Abstract SOLUTIONS OF DIBORANE IN TETRAHYDROFURAN CAN BE PREPARED WITHOUT HANDLING THE GAS BY TREATINGSUSPENSIONS OF SODIUM BOROHYDRIDE IN TETRAHYDROFURAN WITH BORON TRIFLUORIDE, FOLLOWED BY DECANTING, FILTERING, OR CENTRIFUGING ITATED SODIUM FLUOBORATE. SUCH SOLUTIONS ARE NORMALLY UNSTABLE AT ORDINARY TEMPERATURES, UNDERGOING REDUCTIVE CLEAVAGE OF THE SOLVENT. CONSEQUENTLY, THEY CANNOT BE STORED FOR ANY APPRECIABLE TIME OF SHIPPED ANY APPRECIABLE DISTANCE. HOWEVER, THESE SOLUTIONS ARE STABILIZED TOWARD SUCH REDUCTIVE CLEAVAGE BY BY UTILIZING IN THE SYNTHESIS A SLIGHT EXCESS OF SODIUM BOROHYDRIDE OR OTHER IONIC BOROHYDRIDES. THESE DICOVERIES NOW MAKE PRACTICAL THE MANUFACTURE, SHIPPING, STORING AND APLICATION OF SUCH SOLUTIONS OF DIBORANE IN TETRAHYDROFURAN, HIGHLY USEFUL FOR HYDROBORATIONS AND HYDROGENATIONS.
