Exchange of boryl ligand substituents in Os[B(OEt)2]Cl(CO)(PPh3)2

Reaction between Os[B(OEt)2]Cl(CO)(PPh3 2 and 1,2-ethanediol in the presence of Me3SiCl (1 equivalent) leads to the tethered boryl complex, Cl(CO)(PPh3 2 (1), in which one ethoxy substituent on the boryl ligand is exchanged with one hydroxy group of the 1,2-ethanediol leaving the other OH group available to coordinate to osmium, so giving a six coordinate complex. This formulation is confirmed by crystal structure determination. The same reactants, but with 2 equivalents of Me3SiCl, lead to the yellow, coordinatively unsaturated complex, Os Cl(CO)(PPh3)2 (2). Complex (2) adds CO to give Os Cl(CO)2 (PPh3)2 (3). Crystal structure determinations of 2 and 3 reveal a very marked difference in the Os-B distances found in the five coordinate complex 2 (2.043(4) ?) and the six coordinate complex 3 (2.179(7) ?). In a reaction similar to that used for forming 2 but with 1,3-propanediol replacing 1,2-ethanediol, the product is Os Cl(CO)(PPh3 2 (4). The crystal structure for 4 is also reported.
