Abstract

The reaction of 1,1-dibutylstannepin with BCl3 gave 1-chloroborepin, which has been converted to a variety of 1-substituted borepins, C6H6BX, where X = OH, O1/2, OCH3, 2,4,6-Me3C6H2, CH2CH2CH2NMe2, F, NH2, N(CH2)5, N(iPr)2, H. 1-Chloroborepin and 1-aminoborepin have been investigated by ab initio methods. All borepins have been studied using 1H NMR, 11B NMR, and 13C NMR spectroscopy. The X-ray crystal structure of 1-chloroborepin gives evidence of a π-delocalized structure. All properties are discussed in terms of the aromatic character of the borepin ring system.
