The reaction of (CH3)3SiC(Cl)=CRR′ (R = R′ = H; R = H, R′ = CH3; R = R′ = CH3; R = R′ = C6H5) with organolithium, reagents was examined. Alkenylsilanes of structure (CH3)3SiCHCH-alkyl were obtained from (CH3)3SiC(Cl)CH2 and alkyllithium reagents. Substrates with R or R′ ≠ H inhibited addition of the organolithium species to the double bond and led to products derived from chlorinelithium exchange
(CH 3)3 SiC(Cl)= CRR'的反应(R = R'= H; R = H,R'= CH 3 ; R = R'= CH 3 ; R = R'= C 6 H 5)和有机锂,检查了试剂。由(CH 3)3 SiC(Cl)= CH 2和烷基锂试剂获得结构为(CH 3)3 SiCH = CH-烷基的烯基硅烷。R或R'≠H的底物抑制了有机锂物质加到双键上,并导致衍生自氯锂交换的产物(R = R'= C 6 H 5)或从烯丙基甲基位点提取质子(R = H,R'= CH 3; R = R′= CH 3)。
