A mild and practical procedure for the Wittig olefination, promoted by lithium hydroxide and triphenylbenzyl phosphonium bromide, has been set up for the synthesis of stilbenes and styrenes. The experimental conditions allow aromatic, heteroaromatic, unsaturated and saturated aliphatic aldehydes to give final products in good yields.
已经建立了由氢氧化锂和三苯基苄基溴化promote促进的Wittig烯烃化反应的温和且实用的方法,用于合成对苯二酚和苯乙烯。实验条件允许芳族,杂芳族,不饱和和饱和脂族醛以高收率得到最终产物。
