Abstract
The potassium fluoride doped Animal Bone Meal (KF/ABM) was prepared and characterized using several techniques to identify the structural properties. After, it has been used as a new and eco-friendly catalyst for the preparation of from aldehydes and ketones oximes under solvent-free conditions. It is clearly shown that this reaction (using this catalyst) can lead to the corresponding oximes in good yields (80 %) to excellent yields (96 %). In the case of dissymmetric aldehydes and ketones, this catalyst can lead to a mixture of Z- and E- isomers (Z/E = 86/14–90/10). The remarkable advantages of this catalyst are high conversion, short reaction times, cleaner reaction profiles, reusability up to 8 times without significant loss of activity, and reduction in catalyst toxicity.
