    摘要： A process for producing an epoxide represented by general formula (1a) or (1b), which comprises reacting an olefin represented by general formula (2) with a compound containing iodine and an acyloxy ion and treating the reaction product under a basic condition so as to form an oxirane ring on the stereochemically crowded side of the feed olefin. In formulae (1a), (1b) and (2), R¹, R², R³ and R⁴ represent each hydrogen, alkyl, alkenyl, aryl, alkoxy, aryloxy, acyl, alkoxycarbonyl, aryloxycarbonyl, aralkyl, silyl or silyloxy, provided that when each of these groups represents a divalent group, they may be combined together to represent a cyclic group, and that these groups may be the same or different from one another and further may be substituted or branched. The plane formed by the double bond, R¹, R², R³ and R⁴ has one side which is stereochemically more crowded than the other side.

    摘要： A process for converting a multihydroxylated-aliphatic hydrocarbon or ester thereof to a chlorohydrin, by contacting the multihydroxylated-aliphatic hydrocarbon or ester thereof starting material with a source of a superatmospheric partial pressure of hydrogen chloride for a sufficient time and at a sufficient temperature, and wherein such contracting step is carried out without substantial removal of water, to produce the desired chlorohydrin product; wherein the desired product or products can be made in high yield without substantial formation of undesired overchlorinated byproducts. In addition, certain catalysts of the present invention may be used in the present process at superatmospheric, atmospheric and subatmospheric pressure conditions with improved results.
