dc.description.abstract The ligands 2-cyanocyclopentyldiphenylphosphine and 2-cyanocyclohesyldiphenylphosphine were synthesized from 1-cyanocyclopentene and 1cyanocyclohexene by addition reactions using diphenylphosphine and aqueous base as the catalyst. These ligands reacted with Pt(II) and Pd(II) salts to yield complexes of the stoichiometry MX2L2 (X = C1, Br). In these complexes the ligands were found to function as monodentate phosphines. Infrared spectroscopic evidence suggested that the platinum complex was of cis and the palladium complexes were of trans geometries.The reactions of the ligands 2-cyanocyclopentyldiphenylphosphine and 2-cyanocyclohexyldiphenylphosphine or the ligand 2-cyanoethyldiphenylphosphine with the complexes dimethyyl(cyclooctadiene)platinun(II) or methyl) (chloro) (cyclooctadiene) platinum(II) resulted in complexes of the stoichiometries Pt(CH3)2L2 and Pt(CH3)(C1)L2. In these complexes the ligands also functioned as monodentate phosphines. hmr and far infrared spectroscopic evidence suggested that the dimethylplatinuin(II) complexes were cis and the (methyl)(chloro)platinum(II) complexes were trans.A complex of the stoichiometry Pd2Cl4(Ph2PC6H10CN)2 was isolated from the reaction of a 1:1 mole ratio of PdC12 with Ph2PC6H10CN. Far infrared and Raman spectroscopic evidence 'suggested that the complex was a chlorine bridged dieter with the ligands at symmetrical positions. The nitrile groups in this complex reacted rapidly with alcohols to yield monomeric imino ether complexes.The Pt(CH3)(C1)L2 complexes reacted with AgPF6 to yield cationic salts of the stoichiometry [Pt(CH3)L2]n+n with one ligand in each [Pt(CH3)L2]+ unit presumably serving as a bridging ligand and the other as a monodentate phosphine. The coordinated nitrite groups in these complexes reacted slowly with methanol to yield amino ether complexes.
