The nitro group of dimethyl (1-nitromethylalkyl)phosphonates is conveniently converted into a formyl group by reaction with singlet oxygen to give dimethyl (1-formylalkyl)phosphonates. (1-Formylbutyl)diphenylphosphine oxide is prepared by the same reaction.
1-硝甲基烷基)
膦酸二甲酯的硝基通过与单线态氧反应转化为甲酰基,从而得到(1-甲酰基烷基)
膦酸二甲酯。 (1-甲酰基丁基)二苯基氧化膦也是通过同样的反应制备的。
