Compelexes de la ferrotetraphenylporphyrine avec des chlorocarbenes porteurs d'un groupement electroattracteur: Fer(II)(TPP)(CClA), A = CN ou COOC2H5

Abstract Stable iron(II) carbene complexes with a chlorocarbene having an electron-withdrawing group CClA (A = CN and COOC 2 H 5 have been isolated. These complexes have been prepared by reduction of CCl 3 COOC 2 H 5 and CCl 3 CN with the iron tetraphenylporphyrin iron(II)(TPP) in the presence of an excess of reducing agent. The structure of these complexes is established by study of their IR, 1 H and 13 C NMR and mass spectra. Their properties are compared with those of the corresponding carbene complex iron(II)(TPP)(CCl 2 ).

trans-Bonding bidentate macroligands in platinum(II) complexes

Square-planar platinum(II) complexes containing trans-bonding bidentate macroligands, bound through pyridine and an olefin, are described; the large rings involving one platinum atom are 10,11, 13 and 17-membered.
