Solubility of trans-Co2(CO)6 [3,5-bis(CF3)C6H3P(i-C3H7)2] in dense carbon dioxide
摘要:
The title compound (1) was prepared by the reaction of 3,5-bis(CF3)C6H3P(i-C3H7)(2) (L1) and Co-2(CO)(8). Its solubility in super-critical carbon dioxide was measured at varying temperatures and pressures using a modified analytical extraction device. Solubility data were determined in the temperature and pressure ranges between 40 and 70 degrees C and between 100 and 300 bar, respectively. The solubility of 1 is lower compared to (p-CF3C6H4)(3)P, but much higher than for transition metal complexes bearing phosphines without fluorinated substituents. (c) 2004 Elsevier B.V.

synthesis of RuHCl(CO)[P(i)Pr(2)(3,5-(CF(3))(2)C(6)H(3))](2) was carried out, and its Lewis acidity toward Cl- was compared to that of RuHCl(CO)(P(i)Pr(3))(2). In this synthesis, Na(2)CO(3) was shown to be a more effective base than NEt(3), because Na+ can better mask the nucleophilicity of the potential ligand Cl-. An X-ray structure determination of the hydride-free species RuCl(2)(CO)(P(i)Pr(2)Me)(2) shows
