Environmentally Friendly and Efficient Process for the Preparation of β-Hydroxyl Ketones
Wang, Guan-Wu,Zhang, Ze,Dong, Ya-Wei
, p. 18 - 21 (2004)
An environmentally benign and efficient process for the preparation of β-hydroxyl ketones was developed by the practical cross-aldol reactions of 2-acetylpyridine, acetophenone, and cyclohexanone with 4-nitro-, 3-nitro-, and 2-nitrobenzaldehydes in water
