An Investigation of Unique Metal Complexes Produced Using Polystyrene-2,2'-bipyridine as a Support, and Several Hydrogenation Catalysts Derived from this Copolymer

摘要

The cleavage reaction between polystyrene bound pyridine and 2,2'-bipyridine ligands, p-py and p-bipy, and the dimers (Rh(X)(CO)C1)2 (X=CO, (C6H5)3P, or toly13P) were studied. While the p-py cleavages produced products analogous to those found homogeneously, the reactions using p-bipy resulted in the formation of several metal complexes not found in solution. This is at least in part the result of the accessability of the initially formed p-bipy-rhodium complexes to subsequent reactions which cannot occur in the homogeneous case due to precipitation of the rhodium complex initially formed.
