摘要

Abstract: The redox system formazanide ion/tetrazolium ion, realized as an ECE sequence, is conceived as a general device to manipulate both electron-deficient and-surplus centers attached to the carbon atom of this system electronically. In order to introduce this redox substituent as a nucleophilic entity into organic substrates, we generated 2, 3- diaryltetrazolinylidenes 16 as novel heterocyclic carbenes in solution (a) by ...
