摘要：

The first examples of bi-functional borane derivatives based around a 1,2,4,5-tetrasubstituted benzene framework are reported. Synthesis of CIBO2C6H2O2BCl (4) is accomplished in three steps (69% overall yield) through the intermediacy of the trimethylsilyl derivative 1,2,4,5-(Me3SiO)(4)C6H2 (3). The bis(borane) species HBO2C6X2O2BH (X = H, 7; X = Cl, 8) on the other hand, can be synthesised in a single step from substituted para-quinone precursors. Crystal structures are reported for compounds 3 and 4. (C) 2000 Elsevier Science B.V. All rights reserved.
