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.
