Abstract

Abstract : Microwave-assisted syntheses of heavily iodinated 10-vertex and 12-vertex closo boron clusters are reported. Salts of closo -B10 I10 2−, 1-carba- closo -CHB9 H4 I5 −, 1-carba- closo -CB11 H6 I6 −, 1-carba- closo -CHB11 I11 −, and B12 I12 2− were prepared in yields of 80% or better. All molecules were characterized by NMR and IR spectroscopy and mass spectrometry. The crystal structure of [Et4 N][CHB9 H4 I5 ] was determined by single crystal X-ray diffraction. This salt crystallizes in the monoclinic P 2(1)/ c space group, a = 9.74427(12) Å, b = 20.7512(2) Å, c = 13.06589(17) Å, b = 101.2176(12)°, V = 2591.52(6) Å 3, Z = 4, and rc = 2.262 g/cm 3 .
