| Abstract: | The complexes (MH(O2CCF3) (CO) (PPh3)2] and (M(O2CCF3)2(CO)(PPh3)2] (M = Ru or Os) react with terminal and internal acetylenes to afford oligomerisation and hydrogenation products, respectively, together with vinylic complexes, including the ruthenium species Ru(C4HPh2)(O2CCF3)(CO) (PPh3)2], which has been shown by x-ray diffraction methods to contain a 1,4-diphenylbut-1-en-3-yn-2-yl ligand. |
