Process for the manufacturing 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(R.sup.1).sub.2 C(R.sup.1).sub.2 C(R.sup.2).sub.2 C(R.sup.2).sub.2 H wherein each R.sup.1 is independently selected from the group consisting of H, F, Cl, CN, R, OR, CO.sub.2 R, C(O)R, OC(O)R, R.sup.f, OR.sup.f, CO.sub.2 R.sup.f C(O)R.sup.f and OC(O)R.sup.f where R is a hydrocarbyl group and R.sup.f is a C.sub.1 to C.sub.10 polyfluoroalkyl group, provided that at least one R.sup.1 is F, and wherein each R.sup.2 is independently selected from the group consisting of H, F, Cl, CN, R, OR, CO.sub.2 R, C(O)R, OC(O)R, R.sup.f, OR.sup.f, CO.sub.2 R.sup.f, C(O)R.sup.f, OC(O)R.sup.f and difunctional linkages where an R.sup.2 group on each of two adjacent carbon atoms together form a link selected from the group consisting of --CH.sub.2 CH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 CH(CH.sub.3 --, --CH.sub.2 CH(CH.sub.3)CH.sub.2 --, --C(O)OC(O)--, and norborndiyl. The process involves reacting a metallacycle of the formula L.sub.m M(1,4-C(R.sup.1).sub.2 C(R.sup.1).sub.2 C(R.sup.2).sub.2 C(R.sup.2).sub.2 --) wherein R.sup.1 and R.sup.2 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.
