Bayer-Villiger Oxidation | |||||||
Very helpful Rhodium, thank you for posting that article. It improves my understanding of the reaction. Reference 77 Boeseken and Jacobs, Rec. trav. chim. 55, 804 (1936) for phenylacetone may have some tips that could be used to improve this procedure. I believe they used HCl in the hydrolysis step. The hydrolysis should be near quatitative, is that correct? Because I have noticed a lot of clean high boiling golden/red residue after the distillaton and wonder how much could be the unconverted enol ester. If any bee has access to this journal please post it. No library in my vicinity. There are also several references in the catalyst section that could improve the yield. The sulfuric or toluenesulfonic acids might work and if anyone can find some of these I will try it and post the results. As much as possible I want to avoid exotic catalysts. |
