meta-Chloroperoxybenzoic acid (mCPBA or mCPBA) is a peroxycarboxylic acid. It is a white solid often used widely as an oxidant in organic synthesis. mCPBA is often preferred to other peroxy acids because of its relative ease of handling. [1] mCPBA is a strong oxidizing agent that may cause fire upon contact with flammable material. [2]
Although many different peroxyacids are used for the Baeyer–Villiger oxidation, some of the more common oxidants include meta-chloroperbenzoic acid (mCPBA) and trifluoroperacetic acid (TFPAA). [2] The general trend is that higher reactivity is correlated with lower pK a (i.e.: stronger acidity) of the corresponding carboxylic acid (or alcohol ...
Early work showed that allylic alcohols give facial selectivity when using meta-chloroperoxybenzoic acid (m-CPBA) as an oxidant. This selectivity was reversed when the allylic alcohol was acetylated. This finding leads to the conclusion that hydrogen bonding played a key role in selectivity and the following model was proposed.
Government funds. These invest almost entirely in U.S. Treasury bonds and other government assets. They offer the lowest risk but pay less interest because of their safety-first approach. Prime funds.
The UK government generally spends more than it raises in tax. To fill this gap it borrows money, but that has to be paid back - with interest. The government gets most of its income from taxes ...
President-elect Donald Trump is poised to seize greater control of the federal government than any modern president before him when he takes office on Monday, charging ahead with plans to ...
The government often needs to supplement its internal Systems Engineering and Technical Advisory capability in order to meet its frequently changing needs and demands. Through a formal Request for Information (RFI)/ Request for Proposal (RFP) process the government is able to contract with a commercial organization to provide certain services ...
Publication of an otherwise protected work by the U.S. government does not put that work in the public domain. For example, government publications may include works copyrighted by a contractor or grantee; copyrighted material assigned to the U.S. Government; or copyrighted information from other sources. [5]
