Phenyltelluromethyldiphenylphosphine oxide was prepared by the reaction of methyldiphenylphosphine oxide with base and PhTeBr. The telluromethylphosphine oxide reacts with aldehydes and ketones to give the corresponding vinylic tellurides, with preferential E stereochemistry for aryl aldehydes and Z for alkyl aldehydes.
通过甲基二苯基膦氧化物与碱和PhTeBr的反应制备苯基碲甲基二苯基膦氧化物。碲甲基甲基氧化膦与醛和酮反应生成相应的乙烯基碲化物,芳基醛优先采用E立体化学,烷基醛优先采用Z。
