In contrast with previous findings, triethylborane, BEt3, can act as a hydroborating reagent. Thus, the reactions of BEt3 with alkyn-1-yl(trichloro)silanes, di(alkyn-1-yl)dichlorosilanes, alkyn1-yl(dichloro)vinylsilanes, trichloro(vinyl)silane, and dichloro(methyl)vinylsilane for several days in excess BEt3 as the solvent at 100-120 °C were found to give exclusively products of 1,2-hydroboration. This unexpected behaviour was compared with that of tri-n-propylborane, BnPr3, and 9-borabicyclo[3.3.1]nonane, 9-BBN in analogous reactions, 9-BBN being a well established hydroborating reagent. All products were characterised by a consistent set of NMR data (1H, 11B, 13C and 29Si NMR).
