Webm-CPBA is a peroxycarboxylic acid that is commonly used as an oxidizing agent. It is usually available in 77% form because pure m-CPBA is shock sensitive (potentially … Webderivatives by Fe(TPP)Cl and m-CPBA with 95– 100% yields in a few minutes at ambient conditions (Scheme 1). In the initial experiment, 4-methyl substituted DHP was oxidized by m-CPBA in CH 2 Cl 2 at room temperature. We found that the oxidation does not efficiently proceed in the absence of catalyst (<15% yield). punch of color teleflora https://plumsebastian.com
