Synthesis of new phosphine ligands and their metal complexes,the investigating of their solubility in the supercritical carbon dioxide

Catalysis by metal complexes in homogenous solution has undergo important developments in nontraditional raection media such as water, fluorus solvents, ionic liquids and supercritical carbon dioxide (skCO2). On the other hand, the design of stereoselective reactions remains an important challenge in modern organic chemistry and plays a critical role in both pharmaceutical and agrochemical industries.In this project, we synthesized 1,2-bis(bis(4-metilfenil)fosfino)-1,2-dimetilhidrazin (L1) and 1,2-bis(bis(4-metilfenil)fosfino)etan (L2) as a ligands and their rodyum(I) complexes of these ligands [(1, 2-bis (bis (4 - metilfenil) fosfino) - 1, 2-dimetilhidrazin) rodyum (I) (siklooktadien) ]+ BArF- (K1) and [(1,2-bis(bis(4-metilfenil)fosfino)etan) rodyum(I)(siklooktadien)]+ BArF- (K2). Synthesised compounds characterized by using spectroscopic methods such as FT-IR, 1H, 19F, and 31P NMR. Solubility of synthsized compounds in skCO2 was measured at a temperature of 333 K, pressure range of 1500 ? 1550 psi in windowed high pressure reactor.
