cycloaddition can be used as a probe to investigate intramolecular single-electron transfer (SET) mechanisms. The efficacy of intramolecular SET can be evaluated in association with concomitant carbon–carbon bond formation and/or cleavage, leading to cycloaddition or cross-metathesis. Experimental and theoretical results suggest that the intramolecular SET is under both thermodynamic and kinetic control
Although radical cation Diels–Alderreactions enable the formation of cyclohexene ring systems between electronically mismatched (both electron-rich) dienes and dienophiles, which is otherwise difficult or impossible to achieve under thermal conditions, the substrate scope has been limited. Herein, we disclose that a radical cation Diels–Alderreaction using an enol ether as an electron-rich (and therefore

A therapeutic method for treating diseased or injured fish or other aquatic animal includes administering to the fish or other aquatic animal an amount of Pimenta extract selected from the group consisting of Pimenta racemosa and Pimenta dioica sufficient to promote recovery of the diseased or injured fish or other aquatic animal. Also disclosed is a prophylactic method for treating a disease-free fish or other aquatic animal, including adding to water containing or to contain the fish or other aquatic animal Pimenta extract selected from the group consisting of Pimenta racemosa and Pimenta dioica in an amount effective to promote resistance of the aquatic animal to disease. An aqueous emulsion containing Pimenta extract oil in water, where the Pimenta extract is selected from the group consisting of Pimenta racemosa and Pimenta dioica is also disclosed for use in these methods.
