Alcohols have been employed as substrates for C-C bond-forming reactions which involve initial activation by the temporary removal of hydrogen to form an aldehyde. The intermediate aldehyde is converted into an alkene via a Horner-Wadsworth-Emmons reaction, nitroaldol and aldol reactions. The 'borrowed hydrogen' is then returned to the alkene to form a C-C bond.
醇已被用作CC键形成反应的底物,该反应涉及通过暂时除去氢以形成醛而进行的初始活化。中间体醛通过霍纳-沃兹沃思-埃蒙斯反应,硝基醛和醛醇反应转化为烯烃。然后将“借来的氢”返回到烯烃以形成CC键。
