The title compds. I (R = Me, Et, CHMe2, CMe3, Ph) and II were prepd. in 77-97% yields by treating 9-Cl-9-BBN (9-BBN = 9-borabicyclo[3.3.1]nonane) with LiSR (R = Me, Et, CMe3, Ph) in PhMe or C6H6, or 9-BBN dimer with HSR (R = CHMe2, CH2CH2SH) in PhMe. By 11B NMR, all I are monomeric in soln. at room temp. Solid I (R = Me) is a dimer, as detd. by x-ray crystallog. Mixed dimers were prepd. in PhMe soln. from 9-BBN and I (R = Me, Et).
