Abstract
The 1,1-ethylboration of dichloro(hexyn-1-yl)silane, Cl2 Si(H)-C≡C-Bu, affords selectively an alkene which is the first example with dialkylboryl and dichlorosilyl groups in cis-positions at the C=C bond. The analogous reaction of dichloro( trimethylsilylethynyl)silane, Cl2(H)Si-C≡C-Si Me3, leads to a 4:1 mixture of alkenes, in one of which the boryl and dichlorosilyl groups are in trans-positions. The alkenes were characterized by a consistent set of NMR data.
