Perspectives

CHEMISTRY:
Fleeting Molecules Extend Their Stay

Curt Wentrup

Carbenes are molecules with a carbon atom bound to just two other atoms. These species are usually transient intermediates. In his Perspective, Wentrup charts recent progress in the synthesis of stable carbenes. He highlights the report by Solé et al., who have succeeded in synthesizing an unusually stable carbene that retains its reactivity. Such species may find future application as catalysts.
