Abstract

A functionalized magnetic nanoparticle including an organometallic sandwich compound and a magnetic metal oxide. The functionalized magnetic nanoparticle may be reacted with a metal precursor to form a catalyst for various C—C bond forming reactions. The catalyst may be recovered with ease by attracting the catalyst with a magnet.

First claim

The invention claimed is:

1. A ferrocenyl complex represented by any of the following formulas Formula (IA), Formula (IB), Formula (IIA), or Formula (IIB):

where each of R 1 , R 2 , R 3 , R 4 , and R 5 is independently a hydrogen, an optionally substituted alkyl, or an optionally substituted aryl;
R 5′ is a hydrogen, hydroxy, an optionally substituted alkyl, an optionally substituted aryl, an optionally substituted arylalkyl, an optionally substituted alkoxy, an optionally substituted cycloalkyloxy, an optionally substituted aryloxy, or an optionally substituted arylalkoxy;
each of R 6 and R 7 is independently a hydrogen, an optionally substituted alkyl, an optionally substituted aryl, an optionally substituted arylalkyl, an optionally substituted alkoxy, an optionally substituted aryloxy, or an optionally substituted arylalkoxy;
each of R 8 is an optionally substituted alkyl, or an optionally substituted aryl;
a and b are independently an integer in a range of 1-10;
X is O or NH;
M is iron; and
W is an optionally substituted arylene.

2. The complex of claim 1 , wherein R 1 is an optionally substituted alkyl.

3. The complex of claim 1 , wherein R 8 is an optionally substituted aryl.

4. The complex of claim 1 , wherein X is NH.
