Abstract : A report is given of the synthesis of the first boron-permethyl closo-carborane, H2C2B5(CH3)5, a derivative of closo-2,4-dicarbaheptaborane in which all of the borons--and only the borons--are methylated. This compound was prepared by co-pyrolysis of nido-2,3-dicarbahexaborane and boron trimethyl at 300C. Interest in this and related compounds stems from their potential uses as precursors of thermally stable polymers.
