To provide a solid catalyst containing a cyclic imide skeleton which is easily available and easily separable from reaction products and which is easily recovered and regenerated, and free from reaction inhibitory factors; and a process for oxidation of organic compounds with the solid catalyst.
An immobilized cyclic imide catalyst having a structure represented by following Formula (1), wherein X is oxygen or an —OR group (wherein R is hydrogen atom or a hydroxyl-protecting group); n is 0 or 1; Z
1
is a five- or six-membered cyclic imide skeleton to which an aromatic or nonaromatic ring Z
2
may be adjacent; elliptically shaped moiety S is an inorganic support; A
1
is a group linking silicon atom with the cyclic imide skeleton Z
1
or with the ring Z
2
and is either a divalent hydrocarbon group or a group composed of a divalent hydrocarbon group and an amide bond (—NHCO—); and the cyclic imide skeleton Z
1
and the ring Z
2
may each be substituted.
