Abstract

The first syntheses of closo-carboranylcorroles (3, 4, and 11) have been achieved in a one-pot procedure from the condensation of pyrrole and carboranylbenzaldehydes, without the concomitant formation of the corresponding tetraarylporphyrins. The water-soluble nido-carboranylcorrole 9 was prepared from 7 in quantitative yield using tetrabutylammonium fluoride. The first X-ray molecular structure of a Cu(III) carboranylcorrole complex 7 is also presented. Carboranylcorroles absorb in the red region of the optical spectrum and should have potential application in both BNCT and PDT. © 2005 Elsevier Ltd. All rights reserved.
