white crystalline powder

??

Reducing agent for the preparation of plate-type palladium-zinc oxide catalys, reagent for chemical vapor generation and spectrometry determination of elements using amineboranes and cyanotrihydroborate(III) reagents. Catalyst for regioselective reductive opening of benzylidene acetal glycosides and polarity reversal.

Purification Methods

It is sublimed using equipment described in Burg and Schlesinger [J Am Chem Soc 59 780 1937I]. Its vapour pressure is 86mm at 100o. It forms colourless hexagonal crystals varying from needles to short lumps, which are slightly soluble in H2O (1.48% at 30o), EtOH (1%), hexane (0.74%) but very soluble in Et2O, *C6H6 and AcOH. It is stable at 125o. [Burg & Schlesinger J Am Chem Soc 59 780 1937, Brown et al. J Am Chem Soc 104 325 1942, Beilstein 4 IV 140.]
