Certain phosphorus-containing compounds are described herein which are novel latent catalysts for promoting the reaction between vicinal epoxides and phenols and/or carboxylic acids (or anhydrides). Precatalyzed epoxy resins are easily prepared using such catalysts.

Heterocyclic diones of the class containing 3-(heteroarylalkylene)- and 3(arylalkylene)-2, 4 (3H, 5H)-furandiones, and 3-(heteroarylalkylene)-pyrrolidene diones and -thiophene diones are disclosed as being effective cancer chemotherapy drugs, some of which are themselves novel compounds. Various members of this class were tested both in vitro and in vivo to demonstrate their effectiveness at reducing or inhibiting cancer tumor cells. The class of drugs was evaluated against a series of 10 human tumors in the in vitro Human Tumor Cell Assay procedure. The procedure indicates that this class of heterocyclic diones is effective against a broad variety of types of cancer and has little or no toxic effects based upon hematological and pathological evaluations.
