A convenient procedure for the preparation of aldehydes, in good to excellent yields, from suitable olefins by ozonolysis in methanol, followed by exposure of the resulting products to thiourea, is described.
Electrochemical Transformation of epoxides to ketones and acetonides were achieved by using an electrogenerated acid-catalyst. A combination of M(ClO4)n [ M; Li, Na, Mg, n = 1, 2] with polar aprotic solvents [CH2Cl2, ClCH2CH2Cl, THF, CH3COCH3, AcOEt, (MeO)2CO ] is useful for the electrochemical transformation.

The transformations of 6,7-epoxy derivatives of widely spread in the nature unsaturated aldehydes, citral and citronellal, in various acidic media both under conditions of homogeneous and heterogeneous catalysis were investigated. A number of previously unknown products belonging to different classes of organic compounds was obtained. Probable mechanisms of the products formation are discussed.
