Ruthenium(II) complexes of the chelating phosphine borane H2ClB center dot dppm

Conference item

Reaction of H2ClB • PPh2CH2PPh 2 (H2ClB • dppm) with [RuCp*(NCMe)3][BAr4F] (BAr4F=[B{3,5-(CF3)2C6H3}4]-) results in displacement of all three acetonitrile ligands and the formation of [RuCp*(η2-H2ClB·dppm)][BAr4F] (1), which has been characterised crystallographically. Reaction with carbon monoxide results in a change from η2 to η1 of the borane ligand to afford [RuCp*(CO)(η1-H2ClB·dppm)][BAr4F] (2). Compound 1 undergoes H/D exchange under a D2 atmosphere to afford [RuCp*(η2-D2ClB·dppm)][BAr4F], while 2 does not. © 2005 Elsevier B.V. All rights reserved.
