η5-2,3-Dihydro-1,3-diborol-Komplexe des Rhodiums [1] / η5-2,3-Dihydro-1,3-diborole Complexes of Rhodium [1]

Abstract

Reaction between [(C2H4)2RhCl]2 and the 2,3-dihydro-1.3-diborole derivative 1 yields [(l)RhCl]2 (3). In 3 the chloro-bridge can be replaced by the 2,3-dihydro-l,3-diborolyl(1-H) or by the cyclopentadienyl group to give the sandwich complexes 4 and 5, respectively. The complexes 3-5 contain a penta-coordinated carbon atom in the ligand 1. 1H and 11B NMR data are reported.
