NMR studies on reaction of stabilized phosphorus ylide with phthalic anhydride 稳定膦叶立德和邻苯二甲酸酐反应的NMR研究
In these reported reactions, it is generally considered that an in situ formed phosphorus ylide is the key intermediate. 在这些反应中,人们普遍认为反应经过了一个原位生成的磷叶立德活性中间体。
The new phosphorus ylide could react with aldehyde to give trisubstituted alkenes. 这种新型的膦叶立德在有醛存在的条件下,可生成三取代的烯烃。
