Appl Radiat Isot. 2009 Jul;67(7-8 Suppl):S101-4. doi: 10.1016/j.apradiso.2009.03.024. Epub 2009 Mar 26.

Abstract

Conjugates of bacteriochlorin p and chlorin e(6) with cobalt bis(dicarbollide) anion [3,3'-Co(1,2-C(2)B(9)H(11))(2)](-) were synthesized using different synthetic approaches. The boronated bacteriochlorin p was prepared by reaction of bacteriochlorin N-amino cycloimide with, bis(dicarbollide)-based carboxylic acid. The boronated chlorin e(6) conjugates were obtained by both "click reaction" of containing alkyne group chlorine with azide derivative of cobaltacarborane and reaction of chorin-based amines with cyclic oxonium derivative of cobalt bis(dicarbollide).
