Aldehydes are easily converted to 1-bromoolefins or terminal acetylenes by the use of Wittig reaction of bromomethylenetriphenylphosphorane which is prepared from bromomethyltriphenylphosphonium bromide with potassium tert-butoxide.
通过使用由
溴甲基三苯基
溴化phosph与
叔丁醇钾制得的
溴亚甲基
三苯基膦的维蒂希反应,可以容易地将醛转化为1-
溴烯烃或末端
乙炔。
