Purpose of work: To synthesize new d10-metal complexes with allyl derivatrives of phosphine, phosphonic, phosphinic and phosphoric acids. - To create new or improve existing methods for the synthesis of allyl derivatrives of phosphine, phosphonic, phosphinic and phosphoric acids. - To study a synthesized complexes by x-ray methods and IR- spectrometry. - To find a peculiarities of coordination of organophosphorus unsaturated organic ligands on d10-metal centers and features of stereochemical behavior of elementorganic ligand based on the X-ray and spectral data. Methods and apparatus: x-ray structure analysis (automatic single crystal diffractometer "КМ4 CCD XСalibur"), IR-spectroscopic studies (spectrophotometer "Specord М-80"), quantification of complexes compositions (microcolorimeter МКМФ-01). First examples of Cu(I) complexes with phosphorus allylic derivatives were synthesized and X-ray studied: first examples of copper complexes with phosphonium allyl derivatives of composition [CH2=CHCH2(C6H5)3P][CuСl2], [CH2=CHCH2(C6H5)3P][CuBr2], [CH2=CHCH2(C6H5)3P]2[CuBr4], [CH2=CHCH2(C6H5)3P+]2[Сu3Br82-][СuBr] were synthesized from copper(I) halides and allyltriphenylphosphonium bromide; first examples of copper complexes with phosphine oxide allyl derivatives of composition [CuI16CuII((СН2=СН СН2)3P=O)4Cl18]·(H2O)0,5·(C6H6)0,5 and [CuI4CuII0,5(All2PhP=O)2(C2H5OH)Cl5] were synthesized. The ability of allylic phosphine oxides to stabilize two oxidation states of copper - Cu+1 and Cu+2 within the same crystal structure was found. This property is caused by the presence in the molecules of allylic phosphine oxide derivatives of an oxygen atoms, which able to coordinate with hard Lewis acids, particularly with Cu2+, and also caused by the presence in the molecules of a С=С - groups, which able to coordinate with soft Lewi's asids, particularly with Cu2+. It was found, that allylic group does not ?-coordinate to metal atoms in the crystal structures of Cu(I) complexes with allylic phosphonium derivatives. It was found, that phosphorus allylic derivatives can form mixed valence crystal complexes, that contain Copper(I) and Copper(II) atoms. Structural information was deposited to Cambridge Crystallographic Data Centre (CСDC).
