The 9-RS-9-BBN compounds are prepared from 9-Cl-9-BBN with LiSR (1a, b, d, e) or from (9-BBN)2 with HSR (1c, f).All 9-RS-9-BBN compounds are monomeric in solution at room temperature (11B NMR).At or below room temperature two sets of signals for the α-C- and β-C atoms of the C8H14B bicyclic ring are observed in the 13C-NMR spectra of 1a-c and f (hindered rotation around the BS bond). (1a)2 is a dimer in the solid state (X-ray analysis).The mixed dimers 1a-9-BBN and 1b-9-BBN are formed in solution from 1a or 1b with (9-BBN)2 (MS, 11B NMR). (1a)2 reacts with AlCl3, pyridine, or trimethylphosphane to form the crystalline 1:1-addition compounds 1a-AlCl3, Py-1a, and TMP-1a, respectively.
