Abstract

The reaction of B12H11NH3 (1−) with carbodiimides can form guanidinium salts containing the boron cluster. Depending on the side chains of the carbodiimide, these derivatives of the B12H12 (2−) cluster can be uncharged or can carry an overall positive or negative charge. This reaction allows the preparation of B12H11NH3-derivatives with aliphatic side chains, in contrast to the acylation reaction of B12H11NH3-and the formation of Schiff bases, both of ...
