PREPARATION OF BORON-SUBSTITUTED CARBORANES BY BORON INSERTION REACTIONS.
Abstract
The boron insertion reaction of Hawthorne was employed in preparing 3-fluoro-, 3-bromo- and 3-diphenylamino-o-carborane. This reaction was further extended to the m-carborane system to produce 2-fluoro- and 2-diphenylamino-m-carborane. 3-Fluoro-o-carborane could be isomerized at 400C to a mixture of 2-fluoro- and 4-fluoro-m-carborane, which was separated by liquid chromatography on a basic alumina column. Likewise, 3-diphenylamino-o-carborane was isomerized, and the 2-diphenylamino- and 4-diphenylamino-m-carborane isomers were separated by the same technique. (Author)
