Abstract
A heterogeneous metallocarborane catalyst bound to a polymeric support by a carbon-boron bond. Chloromethylated polystyrene beads provide the support. The catalytic beads are characterized as 3,3-(Ph P)-3-H-4 polystyrylmethyl - 3,1,2-Rh C.sub.2 B.sub.9 H.sub.10.
Claims4
A heterogeneous catalyst for the hydrogenation and isomerization of olefins, said catalyst consisting of:
- the polymer-bound rhodacarborane 3-3-(Ph.sub.3 P).sub.2 -3-H-4 polystyryl methyl-3,1,2-Rh C.sub.2 B.sub.9 H.sub.10.
A method of forming a polymer-bound heterogeneous rhodacarborane catalyst for the hydrogenation and isomerization of olefins comprising:
- reacting preformed polystyrene beads with C.sub.2 B.sub.9 H.sub.11.sup.- to obtain a bead-like product, and
- reacting said product with a rhodium compound to obtain said polymer-bound rhodacarborane as a final product,
- the general composition of said final product being a metallocarborane directly bound to said preformed bead.
