Wittig试剂

Wittig反应是醛酮与含磷的试剂——烃代亚甲基三苯基膦反应，生成相应的烯类化合物。该反应收率高、反应条件温和，是近年来在有机合成方法上发展较快地反应之一。G. Wittig正是由于此反应及相关的研究荣获了1979年的诺贝尔化学奖。 CAS 产品名称 包装 1779-49-3 甲基三苯基溴化膦 25 g Methyltriphenylphosphonium bromide, 98% 100 g 1560-54-9 烯丙基三苯基溴化膦 25 g Allyltriphenylphosphonium bromide, 99% 100 g 1779-51-7 正丁基三苯基溴化膦 10 g n-Butyltriphenylphosphonium bromide, 99% 25 g 6048-29-9 苯甲酰甲基三苯基溴化膦 25 g Phenacyltriphenylphosphonium Bromide, 97% 13423-48-8 庚基三苯基溴化膦 25 g Heptyltriphenylphosphonium Bromide, 98% 1449-46-3 苄基三苯基溴化膦 25 g Benzyltriphenylphosphonium Bromide, 97% 14114-05-7 环丙基三苯基溴化膦 5 g Cyclopropyltriphenylphosphonium Bromide, 97% 3607-17-8 3-溴丙基三苯基溴化膦 25 g 3-Bromopropyltriphenylphosphonium Bromide, 98% 1034-49-7 溴甲基三苯基溴化膦 5 g (Bromomethyl)triphenylphosphonium Bromide, 98% 25 g 2091-46-5 炔丙基三苯基溴化膦 5 g Triphenylpropargylphosphonium Bromide, 98% 25 g 82105-88-2 4-乙氧苄基三苯基溴化膦 5 g 4-Ethoxybenzyltriphenylphosphonium Bromide, 98% 25 g 4762-26-9 己三苯基溴化膦 25 g Hexyltriphenylphosphonium Bromide, 98% 1100-88-5 苄基三苯基氯化膦 25 g Benzyltriphenylphosphonium chloride, 99% 100 g 4336-70-3 (氰甲基)三苯基氯化膦 25 g (Cyanomethyl)triphenylphosphonium Chloride, 98% 5293-84-5 (氯甲基)三苯基氯化膦 5 g (Chloromethyl)triphenylphosphonium Chloride, 98% 25 g 4009-98-7 甲氧基甲基三苯基氯化膦 25 g (Methoxymethyl)triphenylphosphonium chloride, 98% 4736-60-1 乙基三苯基碘化膦 25 g Ethyltriphenylphosphonium iodide, 95% 2065-66-9 甲基三苯基碘化膦 25 g Methyltriphenylphosphonium iodide, 97% 24470-78-8 异丙基三苯基碘化膦 5 g Isopropyltriphenylphosphonium iodide,98% 25 g 1439-36-7 1-三苯基膦烯-2-丙酮 25 g 1-Triphenylphosphoranylidene-2-propanone, 99% 16640-68-9 (三苯基膦)乙腈 5 g (Triphenylphosphoranylidene)acetonitrile, 98% 2136-75-6 甲酰甲撑基三苯基膦 5 g (Triphenylphosphoranylidene)acetaldehyde, 97% 2605-67-6 (三苯基膦烯)乙酸甲酯 5 g Methyl (triphenylphosphoranylidene)acetate, 98% 25 g
