[C36H30NP2][B3O3(OH)4]·2.5H2O (8), 4,4′-bipiperidinium heptaborate dihydrate [C10H22N2][B7O9(OH)5]·2H2O (9). All compounds were characterized by thermal (TGA/DSC) and spectroscopic (NMR, IR) analysis. Compounds 3–5 and 9 were characterized by single-crystal XRD studies. The waters of crystallization in 3–6 and the boric acid of crystallization in 3 play important structural roles in expanding the supramolecular

Disclosed is a method for producing an olefin oxide, capable of overcoming the disadvantage of the conventional methods that hydrogen peroxide is not completely consumed and thus is left to remain, depending on the reaction conditions. To solve this problem, the method of the present invention comprises the steps of [1] reacting hydrogen peroxide with an olefin in the presence of a titanosilicate and a solvent, and [2] bringing the reaction product obtained in the previous step, into contact with a substance containing at least one element selected from the group consisting of manganese and platinum group elements.
