Provided is a highly efficient method for the production of aldehydes and ketones, which is inexpensive, exhibits high reactivity, and is capable of easy separation of byproduct after the reaction. More particularly, there is provided a method for producing an aldehyde or a ketone, comprising at least an oxidation step of oxidizing a primary alcohol or a secondary alcohol in the presence of a polymeric carbodiimide represented by the following formula (1) and having a weight-average molecular weight of 300 to 5000, and a sulfoxide compound, together with an acid and a base, or together with a salt of the acid and the base.
R1―N=C=N―(R3―N=C=N)―nR2 (1)
本发明提供了一种生产醛和酮的高效方法,该方法成本低廉,反应活性高,且反应后的副产物易于分离。更具体地说,本发明提供了一种生产醛或酮的方法,该方法至少包括一个氧化步骤,即在由下式(1)表示的、重量平均分子量为 300 至 5000 的聚合物碳二亚胺和亚砜化合物以及酸和碱或酸和碱的盐的存在下,氧化伯醇或仲醇。
R1-N=C=N-(R3-N=C=N)-nR2 (1)
