AbstractAt the transition metal sulfur center of [Ru(PPh3)2dttd], (dud2- = 2,3;8,9-dibenzo-1,4,7,10- tetrathiadecane( -2)), the substitution of one PPh3 ligand by anions like N3- or CN- in CH2Cl2 is always coupled with a chloromethylation of one thiolato S atom in dttd2- yielding the [dttd-CH2Cl]- ligand; with N3- conversion of azido into cyano ligands takes place additionally. In the reaction of [Ru(PPh3)2dttd] with covalent azides like Me3SiN3 or HN3, the PPh3 substitution is also coupled with the oxidation of Ru(II) to Ru(III). Thus [Ru(PPh3)2dttd] on reaction with NEt4N3 or NEt4CN in boiling CH2Cl2 yields [Ru(PPh3)(L)(dttd-CH2Cl)], (L = N3-, CN-), whereas with Me3SiN3 or HN3 in addition to [Ru(PPh3)(N3)(dttd-CH2Cl)] the paramagnetic (μeff = 1.58 B.M.) [Ru(PPh3)(N3)(dttd)] is obtained. The very stable [Ru(PPh3)(CN)(dttd-CH2Cl)] forms deeply coloured adducts with H+ as well as [CrCl3(THF)3], AlCl3 and BF3. With Mel it yields [Ru(PPh3)(CN)(Me-dttd-CH2Cl)]I. All compounds have been characterized by elemental analysis as well as spectroscopic means including ESCA; the structure of [Ru(PPh3)(CN)(dttd-CH2Cl)] has been solved by X-ray structure analysis.
