PROCESS FOR THE MANUFACTURE OF SELECTED HALOGENATED HYDROCARBONS CONTAINING FLUORINE AND HYDROGEN AND COMPOSITIONS PROVIDED THEREIN

摘要

A process is disclosed for the manufacture of product compounds of the formula HC(R1)2C(R1)2C(R2)2H wherein each R1 is independently selected from the group consisting of H, F, Cl, CN, R, OR, CO¿2?R, C(O)R, OC(O)R, R?f, ORf, CO¿2R?f, C(O)Rf¿ and OC(O)Rf where R is a hydrocarbyl group and Rf is a C¿1? to C10 polyfluoroalkyl group, provided that at least one R?1¿ is F, and wherein each R2 is independently selected from the group consisting of H, F, Cl, CN, R, OR, CO¿2?R, C(O)R, OC(O)R, R?f, ORf, CO¿2R?f, C(O)Rf¿, OC(O)Rf and difunctional linkages where an R2 group on each of two adjacent carbon atoms together form a link selected from the group consisting of -CH¿2?CH2CH2-, -CH2CH2CH2CH2-, -CH2CH2CH(CH3)-, -CH2CH(CH3)CH2-, -C(O)OC(O)-, and norborndiyl. The process involves reacting a metallacycle of the formula LmM(1,4-C(R?1)¿2C(R1)2C(R2)2C(R2)2-) wherein R?1 and R2¿ are as defined above, and wherein M is a metal selected from the group consisting of Group 8, Group 9 and Group 10 metals, each L is a ligand selected from the group consisting of Group 14, Group 15 and Group 16 ligands, and m is an integer from 1 to 4, in the liquid phase with hydrogen. Also disclosed are certain compositions comprising product compounds within the above product compound formula and certain metallacycle compounds within the above metallacycle formula.
