1,2-Hydroboration of Alkyn-1-yl(chloro)silanes: Alkenes Bearing Chlorosilyl and Dialkylboryl Groups in Geminal Positions
نویسندگان
چکیده
The 1,2-hydroboration of various alkyn-1-yl(chloro)silanes (3 – 7), derived from 1-hexyne (a) and ethynylbenzene (b), using 9-borabicyclo[3.3.1]nonane, 9-BBN, affords selectively alkene derivatives in which the dialkylboryl and chlorosilyl groups are in geminal positions at the C=C bond. The molecular structure of (Z)-α-(9-borabicyclo[3.3.1]non-9-yl)-α-dichloro(phenyl)silyl-styrene (11b) was determined by X-ray diffraction. All alkenes were characterised by a consistent set of NMR spectroscopic data (1H, 11B, 13C, 29Si NMR).

Reactivity of Triethylborane towards Di(alkyn-1-yl)(chloro)silanes. Competition between 1,1-Organoboration and 1,2-Hydroboration
Reactions of di(alkyn-1-yl)(chloro)silanes, HSi(Cl)(C≡C-R)2, RSi(Cl)(C≡C-R)2 or HSi(Cl)(C≡C-R)C≡C-R′, with an excess of triethylborane, BEt3, proceed slowly (several days) at 100 – 120 ◦C. Twofold 1,1-organoboration of HSi(Cl)(C≡C-R)2 or HSi(Cl)(C≡C-R)C≡C-R′ leads to siloles, independent of R = nBu, tBu, SiMe3. This provides the most straightforward way to siloles bearing both a hydrogen and a ...

The reactions of n-hexyn-1-ylsilanes or arylethyn-1-ylsilanes, bearing methyl groups and one (2), two (3) or three hydride functions (4) at the silicon atom, with triallylborane 1 lead primarily to products of 1,1or 1,2-allylboration. In the alkenes (5, 9, 13) formed by stereoselective 1,1-allylboration, with the silyl and the diallylboryl groups in cis-positions at the C=C bond an electron-def...

Hydroboration of the electron poor phosphine (1-propenyl)P(C(6)F(5))(2) with Piers' borane [HB(C(6)F(5))(2)] gave the geminal frustrated Lewis pair (C(6)F(5))(2)P-CH(Et)-B(C(6)F(5))(2). It undergoes 1,2-addition reactions to an alkene and an alkyne and to the C=N bond of an isocyanate. With mesityl azide it undergoes a 1,3-addition reaction.

To further investigate the α-effect in silanes bearing a geminal donor atom, the model compounds (C2F5)3SiCH2NMe2, (C2F5)3SiCH2OMe and (C2F5)3SiONMe2 were prepared by introduction of pentafluoroethyl groups via nucleophilic substitution of the corresponding chloro-derivatives with pentafluoroethyl lithium. The substances were characterised by NMR spectroscopy and X-ray diffraction via in situ c...

Hydroboration of propyne and 1-butyne with HBCl2 obtained from BCl3 and Me3SiH in equimolar amounts leads to 1,1-bis(dichloroboryl)alkanes 1. When BCl3 is used in excess, no 1,1-bis(dichloroboryl)alkanes 1 but E-1-dichloroborylalkene 2 besides E-1-dichloroboryl-2chloro-alk-1-ene 3 are formed. Other by-products are tris(2-chloro-alk-1-ene-1-yl)borane 4 and bis(2-chloro-alk-1-ene-1-yl)chloroboran...
