Abstract
The fluorine substituted thiourea 2,6-F2C6H3C(O)NHC(S)NEt2 was prepared in good yield from the reaction of 2,6-F2C6H3C(O)Cl with KSCN and Et2NH in acetone. Using this compound several heteroleptic, monocationic Pd(II), Pt(II) and Ru(II) complexes of the type cis-[M{κ2S,O-2,6-F2C6H3C(O)NC(S)NEt2}(L)]PF6 [M = Pt, Pd; L = (Ph3P)2, tBu2bipy, 1,10-phen] as well as [Ru(η6-p-cym){κ2S,O-2,6-F2C6H3C(O)NC(S)NEt2}(PPh3)]PF6 were prepared in high yields. The compounds were characterised by spectroscopic methods and, in one case, by single crystal X-ray diffraction.
