Syntheses of carboranylpyrroles
Abstract
The syntheses of three carboranylpyrroles (5, 10 and 14) bearing carborane cages in 3-position and/or 4-position of the pyrrole ring, either directly linked or through a methylene spacer, are described. Tetramerization of two carboranylpyrroles afforded the corresponding β-carboranylporphyrins, as mixtures of type I-IV isomers. © 2001 Elsevier Science Ltd. All rights reserved.
