The effect of the structure of silanes on selectivity of hydrosilylation of 1-hexine

Hydrosilylation of 1-pentyne by triethylsilane catalyzed by phosphine-rhodium complexes

“…The hydrosilylation of 1-hexyne by triethylsilane catalyzed by chloroplatinic acid or octacarbonyldicobalt(0) has been reported to yield trans-1-triethylsilyl-1-hexene and 2-triethylsilyl-1-hexene (eq. 1) [1,2]. The trans-1triethylsilyl-1-hexene being formed by cis-addition of the silane.…”

Addition of Nitrile Oxides to Silyl- And Germyl-Disubstituted Ethylenes

“…According to literature data, the hydrosilylation of mono-substituted acetylenes with trialkyl-and triarylsilanes in the presence of H 2 PtCI 5 leads, in most cases, to a mixture of £-(ß-isomer) and geminal (α-isomer) products [15][16][17][18][19][20][21][22][23][24][25], The Ε-Configuration of the ß-isomer is the result of a c/s-addition to the triple C^C bond of acetylenes [26][27][28], The ratio of the a-and ß-fEj-isomers formed in the reaction 656 Brought to you by | Purdue University Libraries Authenticated Download Date | 6/13/15 9:59 PM strongly depends upon the electron acceptor properties of the substituent R in the acetylene derivatives ROCH.
