|Title:||Epoxides produced by the oxidation of olefins with air or oxygen|
|Abstract:||Catalysts for the selective epoxidization of olefins with atmospheric oxygen, processes for their preparation and processes for the preparation of epoxides by oxidation of olefins with air or oxygen. Compounds of the formula (1) as catalysts for the selective epoxidization of alkenes in which the indices x, y and z have the following meaning: x is a whole number from 1 to 3, y is a whole number from 1 to 2x+1, y being selected so that the sum of x+z gives a metal oxidation number of +5 (vanadium) or +6 (molybdenum, ruthenium); z is a whole number in the range from 2 to 2x; M is molybdenum, ruthenium or vanadium and L is an N, 0 or S donor ligand. Heterogeneous catalysts for the selective oxidation of olefins in the presence of oxygen, comprising an inorganic or organic support material and compounds of the formula (1), and a process for the selective epoxidization of alkenes of the formula ##STR1## with atmospheric oxygen in the presence of a catalyst of the formula (1) are also described.|

The estimated expiration dates shown above are derived by simply adding 20 years to the priority date.
Due to the complexity of determining patent expirations even in a single country, compounded by the diversity of global patent laws, it is advisable to have patent counsel verify freedom to operate.
