    • Tin catalysts are provided for epoxidizing olefinic compounds in the presence of organic hydroperoxides, in the liquid phase. These catalysts give good yields of the epoxide and of the alcohol derived from the organic hydroperoxide. They have the formula: RR 'SnCl.sub.2 (I) in which:R represents a wholly aliphatic or cycloaliphatic or aromatic or mixed aliphatic/aromatic, aliphatic/cycloaliphatic or cycloaliphatic/aromatic, inter alia alkylaryl or aralkyl, linear or branched, saturated or unsaturated monovalent hydrocarbon radical, which can optionally carry substituents, such as chlorine atoms, the number of carbon atoms being at most 20,R' represents either a chlorine atom or a monovalent organic radical of the formula: R"--Y (II) in which:Y represents an oxygen atom, or a (--O--O--) group, or a carbonyloxy group (--CO--O--), the radical R" being attached to the carbon atom of the (--CO--O--),R" may be identical or different to R and is as defined under R.
