Aj. Ashe et al., STRUCTURAL EVIDENCE OF THE AROMATICITY OF BOREPINS - A COMPARISON OF 1-CHLOROBOREPIN AND TRICARBONYL(1-CHLOROBOREPIN)MOLYBDENUM, Angewandte Chemie, International Edition in English, 32(7), 1993, pp. 1065-1066
A planar structure with C2v symmetry is a description of 1-chloroborep
in 1, and is consistent with the presumption that 1 and probably also
1H-borepin are aromatic compounds. The Mo(CO)3 complex was prepared fr
om 1. Its structure was also determined, and it could be reduced to th
e stable complex 2.
