摘要

Catecholborane was conveniently synthesized by the reaction of tri-O-phenylene bis-borate (2) with diborane in triglyme or tetraglyme at moderate temperatures (70-80° C). The product, catecholborane, can be distilled out in 85% yield with> 97% purity. The tri-O- phenylene bis-borate also reacts with borane-Lewis base complexes, such as BH3: DMS, BH3: THF, and BH3: NR3, with or without solvent, providing catecholborane of high purity ...
