摘要:The invention relates to aminated compounds bearing at least an allyl and a difluoromethyl and a method used for synthesis thereof. Said compounds comprise at least one carbon bearing: an amine function, an allyl or propargyl radical, a difluoromethylene group, and a hydrogen or a hydrocarbon radical, advantageously selected among those which are electron donors or hardly electroattractive (; 0. 1). The invention is useful for synthesis of fluorinated compounds.

权利人:AGROFRESH INC
摘要:The present invention generally relates to the regulation of plant physiology, in particular to methods for inhibiting the ethylene response in plants or plant products, and has three embodiments. The first embodiment relates to methods of minimizing impurities capable of reversibly binding to plant ethylene receptor sites during the synthesis of cyclopropene and its derivatives such as methylcyclopropene, thereby avoiding the negative effects these impurities have on plants treated with cyclopropene and its derivatives. The second embodiment relates to complexes formed from molecular encapsulation agents such as cyclodextrin, and cyclopropene and its derivatives such as methylcyclopropene, in addition to cyclopentadiene and diazocyclopentadiene and their derivatives, thereby providing a convenient means for storing and transporting these compounds capable of inhibiting the ethylene response in plants, which are reactive gases and highly unstable because of oxidation and other potential reactions. The third embodiment relates to convenient methods of delivering to plants these compounds capable of inhibiting the ethylene response in the plants in order to extend their shelf life.
