ABSTRACT The reactivity of Ru(O2CNiPr2)2(CO)2(PPh3)2 (1), towards CF3SO3H (TfOH, trifloromethanesulfonic acid or triflic acid) has been studied and the products [Ru(O2CNiPr2)(CO)2(PPh3)2][OTf] (2), and Ru(OTf)2(CO)2(PPh3)2 (3), have been obtained, the former being structurally characterised as one of the few examples of cationic N,N-dialkylcarbamato complexes.

Treatment of this derivative in refluxing toluene followed by addition of methanol afforded the compound [RuH(CO)2(PPh3)2(CH3OH)][OTf] (5), which has been characterised by single-crystal X-ray diffractometry.

Abstract

ABSTRACT The reactivity of Ru(O2CNiPr2)2(CO)2(PPh3)2 (1), towards CF3SO3H (TfOH, trifloromethanesulfonic acid or triflic acid) has been studied and the products [Ru(O2CNiPr2)(CO)2(PPh3)2][OTf] (2), and Ru(OTf)2(CO)2(PPh3)2 (3), have been obtained, the former being structurally characterised as one of the few examples of cationic N,N-dialkylcarbamato complexes. In compound 2, the N,N-di-iso-propylcarbamato group is bidentate. In experiments aimed at obtaining Ru(OTf)2(CO)2(PPh3)2 according to the literature method, i.e. from Ru(CO)3(PPh3)2 and TfOH, the intermediate species [RuH(CO)3(PPh3)2][OTf] (4), corresponding to the oxidative addition of triflic acid, has been intercepted. Treatment of this derivative in refluxing toluene followed by addition of methanol afforded the compound [RuH(CO)2(PPh3)2(CH3OH)][OTf] (5), which has been characterised by single-crystal X-ray diffractometry.
