Polyboron Spiro-Cations Based on Bridging Dipyrazol-1-Ylboryl Units.
Abstract
Syntheses are described for polyboron spiro-cations which were obtained by rection of B-(pyrazol-l'-yl)pyrazaboles with (CH3)3NBH2I or (C2H5)2BOts (ts = tosyl), respectively. In addition, an intermediate species containing both terminal and bridging pyrazolyl groups was identified and characterized. NMR data of the various species are reported; specific assignments of 1H and 13C signals to individual pyrazolyl groups were made on the basis of HOMCOR and HETCOR 2D NMR studies. Originator supplied keywords include: Dipyrazolyboryl-based cations, Polyboron spiro-cations, NMR spectra.
