Synthesis of a BDPA-TEMPO biradical

Org Lett. 2009 May 7;11(9):1871-4. doi: 10.1021/ol9001575.

Abstract

The synthesis and characterization of a biradical containing a 1,3-bisdiphenylene-2-phenylallyl (BDPA) free radical covalently attached to a 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) free radical are described. The synthesis of the biradical is a step toward improved polarizing agents for dynamic nuclear polarization (DNP).
