Abstract Arytellurol complexes [PtCl (TeAr)(PPh 3) 2](I) and [Pt (TeAr) 2 (PPh 3) 2](II) are readily obtained from cis-[PtCl 2 (PPh) 3) 2] and NaTeAr (Ar= C 6 H 5, 4-CH 3 OC 6 H 4 and 4-CH 3 CH 2 OC 6 H 4) in ethanolbenzene at room temperature. 31 P NMR spectra of (I) and (II) indicate their trans configuration in solution. Metathetical reactions between I (Ar= 4- CH 3 OC 6 H 4) and NaX (X= I, Br, SCN) occur in methanol to give [Pt (X)(TeC 6 H 4 OCH ...
