Synthesis and Complexation Behavior of the Functionalized Tripodal Phosphane cis,cis-1,3,5-Tris(cyano)-1,3,5-tris(diphenylphosphanyl)cyclohexane (tdppcycn)

The synthesis of the novel potentially bistripodal ligand cis,cis-1,3,5-tris(cyano)-1,3,5-tris(diphenylphosphanyl)cyclohexane (tdppcycn) (6) is described.Starting from the tricarboxylic acid cis,cis-1,3,5-C6H9(COOH)3 (1), which is converted stepwise into triacid chloride cis,cis-1,3,5-C6H9(COCl)3 (2), the triphenyl ester cis,cis-1,3,5-C6H9(COOPh)3 (3), the tricarboxamide cis,cis-1,3,5-C6H9(CONH2)3 (4), and the tricarbonitrile cis,cis-1,3,5-C6H9(CN)3 (5), we obtained tdppcycn (6) by α-deprotonation of 5 followed by treatment with ClPPh2 in good yield.Treatment of 6 with Mo(CO)3(η6-C7H8) and Ir(PPh3)2(CO)Cl gave octahedral Mo(tdppcycn)(CO)3 (7) and pentacoordinate Ir(tdppcycn)(CO)Cl (8), respectively, with a facially P-coordinated tdppcycn ligand.The stereochemistry of compounds 2-8 was established by 1H-, 13C-, 31P-NMR, and IR spectroscopy.An X-ray crystal structure analysis of complex 8 confirms the trigonal-bipyramidal ground-state structure in the solid state. - Keywords: Phosphane ligands, tripodal; Molybdenum complexes; Iridium complexes
