31. Due to this equilibrium, borane and diborane ( 6 ) are often considered to be chemically equivalent. 32. At-78.5 �C methyldiborane disproportionates slowly first to diborane and 1, 1-dimethyldiborane. 33. The only known method of producing diborane ( 4 ) is the successive abstraction of hydrogen from atomic fluorine. 34. The laboratory was asked to provide a large amount of the product for testing, but diborane was in short supply. 35. They discovered that lithium hydride reacts with boron trifluoride in ethyl ether, allowing them to produce diborane in larger quantities. 36. The nuclear resonance shift for the bridge hydrogen is 8.90 ppm, compared to 10.49 for diborane . 37. The nuclear resonance shift for the bridge hydrogen is 9.27 ppm, compared to 10.49 for diborane . 38. The nuclear resonance shift for the bridge hydrogen is 10.09 ppm, compared to 10.49 for diborane . 39. Polysilicon may be grown directly with doping, if gases such as phosphine, arsine or diborane are added to the CVD chamber. 40. "' Diborane "'is the chemical compound consisting of boron and hydrogen with the formula B 2 H 6.
