  苯硒酸及其前体催化的α，β-不饱和醛与过氧化氢的反应

  摘要：

  研究了苯硒酸及其前体催化的过氧化氢对α，β-不饱和醛的氧化作用。已证明双2-硝基苯基二硒化物是最有效的催化剂。氧化产生的主要产物是乙烯基甲酸酯（a），与起始的醛相比，乙烯基甲酸酯（a）在水解时得到饱和的醛或酮（g），其碳链缩短了一个碳原子。次要产物是甲氧基氧肟酮（b），α-羟基羰基（e）和α-甲氧基羰基（f）化合物，其碳链缩短了一个碳原子。也已经分离出正式衍生自碳-碳双键的氧化裂变的羰基化合物d。当肉桂醛（4）或1-苯基-2-甲酰氧基丙烷（5a）分别被氧化时，已分离出二甲酰氧基（4c）和甲酰氧基乙酰氧基苯基甲烷（5c）。讨论了这些产物形成的可能机理。当α，β-不饱和醛被有机过氧酸氧化时，得到类似的产物。

  The invention relates to a cooling sensation agent composition with a prolonged cool sensation effect comprising at least one compound selected from Formula (1) wherein each of A and B is a hydrogen atom or a hydrocarbon group which may have one or more substituents, in which A and B are not hydrogen atoms simultaneously, and the total number of carbon atoms in A and B is in the range of 6 to 18; and Formulae (2) to (4) wherein R1, R2, and R3 each represent a residue of an alcohol selected from 1-menthol, 1-isopulegol, 3-(1-menthoxy)propan-1,2-diol, 2-(1-menthoxy)ethan-1-ol, 3-(1-menthoxy)propan-1-ol, 2-methyl-3-(1-menthoxy)propan-1,2-diol and para-menthan-3,8-diol), and R4 represents a residue of a branched or straight-chain, cyclic or linear, or saturated or unsaturated alcohol having 6 to 18 carbon atoms that may have one or more aromatic rings that may have a condensed ring and substituent groups such as hydroxyl and ether groups; and R6 represents a hydrocarbon group having 11 to 19 carbon atoms that may be branched and contain one or more unsaturated bonds. The invention also relates to a sensory stimulation agent composition comprising the cooling sensation agent composition; a flavor or fragrance composition, a beverage or food product, a perfume or cosmetic product, a toiletry product, a daily utensil product or grocery, a fiber, a fiber product, a cloth or a medicine comprising the cooling sensation agent composition or the sensory stimulation agent composition; a production method thereof; a cooling processing method of a fiber, fiber product or a cloth, comprising compounding the cooling sensation agent composition or the sensory stimulation agent composition; and new compounds.
