Abstract

The reaction of [PtX2(L)] (x = Cl Br I L = NH2CH2CH2NY2 Y = Et Me) with thallium(I) carbonate and a polyfluorobenzene (RF) in pyridine (py) yields the platinum(II) complexes [Pt N(R)CH2CH2NY2 X(py)] (R = C6F5 4-HC6F4 4-BrC6F4 or 4-IC6F4 Y = Et (1) Me (2) X = Cl Br or I) in an Improved synthesis From the reaction of [PtCl2(H2NCH2)(2))] with Tl2CO3 and 1 2 3 4-tetrafluorobenzene or 2-bromo-1 3 4 5-tetrafluorobenzene in py the new complexes [Pt(NRCH2)(2)(PY)(2)] (3) (R = C6H2F3-2 3 6 and C6HBrF3-2 3 5 6) have been isolated but the latter preparation also gave product(s) with a 4-bromo-2 3 5-trifluorophenyl group From an analogous preparation in 4-ethylpyridine (etpy) [Pt(N(4-HC6F4)CH2)(2)(etPY)(2)] (4) was obtained The X-ray crystal structures of (3) (R = C6HBrF3-2 3 5 6) and (4) were determined as well as that of the previously prepared (3) (R = 4-BrC6F4) and a more precise structure of (3) (R = 4-HC6F4) has been obtained
