Boron-Containing Coumarins (Review).

Synthesis methods, properties, and application fields of various boron-containing coumarin derivatives are summarized. Particular attention is paid to derivatives with various polyhedral boron clusters as substituents, such as carboranes, metallacarboranes, and the closo-dodecaborate anion. Derivatives of coumarin with simple organoboron compounds, boronic acids and their esters, are also considered. [ABSTRACT FROM AUTHOR]
