摘要：

Solution pyrolysis of arylphosphonium salts of B12H122,1, utilizing microwave heating provided charge-compensated monophosphine dodecaborate derivatives of general formula B12H11(PPhnR3-n) (n = 1, R = Me; n = 2, R = Me, Et) in high yield. The resulting anions B-11, H-1, C-13, and P-31 NMR spectroscopy, and by negative mode ESI-TOF mass spectrometry. A single-crystal X-ray diffraction study of [Ph3PMe]2 confirmed an icosahedral boron cluster fragment appended by a PPh2Me moiety through a P-B bond. (C) 2018 Elsevier B.V. All rights reserved.
