Triruthenium dodecacarbonyl reacts with high pressure PF3 or with PF3/CO mixtures to yield two series of compounds. At high PF3 pressures, the mononuclear species Ru(PF3)x(CO)5−x (x = 5, 4 and 3) are the main products with only traces of Ru(PF3)2(CO)3 and Ru(PF3)(CO)4 being found. With high carbon monoxide pressure and less PF3, the species Ru3(PF3)y(CO)12−y (y = 0–6) are the main products. It is seen that Ru3(CO)12 can have up to six CO groups replaced sequentially before the cluster is broken followed by the formation of the mononuclear species. The evidence shows that the Ru(PF3)x(CO)5−x species are stereochemically non-rigid. |
