摘要:
A method of preparing a cyclopropane ring-bearing compound of the formula (I) in which R 1 and R 2 are independently selected from C 1 -C 10 alky], optionally substituted, or R 1 and R 2 together with the bonds linking them to the cyclopropane ring, form a monocyclic or bicyciic ring system, which may comprise at least one hetero-atom, comprising the reaction of a compound of formula (II) in which R 1 and R 2 have the significances hereinabove defined, with a compound of formula (III) in which X is selected a nucieofuge selected from halides and pseudohalides and Y is an electro flige selected from boranes and borates, in the presence of a metal catalyst complex selected from those that a useful for catalytic cyclopropanation and those useful for catalyzing Heck coupling. The method prov ides a particularly easy and non-hazardous method of cyclopropanation.

摘要:
A process for extracting a compound or composition of matter from a raw material containing that compound or composition as a constituent part is described. The process comprises the steps of (1) contacting the raw material with an extraction solvent comprising a pentafluoropropane so as to extract the compound or composition from the raw material into the solvent, and (2) separating the solvent containing the extracted compound or composition from the raw material. The process is particularly adapted for extracting flavours and fragrances from materials of plant origin.
摘要:
The present invention is directed to a continuous process for producing a desired hydrocarbon product using a heterogeneous slurry catalyst, to the product of said process, and to the reactor utilized in such process.
摘要:
Processes of making [1.1.1]propellane utilize reaction conditions that include reacting 1,1-dibromo-2,2-bis(chloromethyl)cyclopropane with an effective amount of solid magnesium.
摘要:
Processes for making bicyclic compounds and precursors thereof, and particularly for making [1.1.1]propellane and bicyclo[1.1.1]pentane and derivatives thereof, utilize continuous flow reaction methods and conditions. A continuous process for making [1.1.1]propellane can be conducted under reaction conditions that advantageously minimize clogging of a continuous flow reactor. A continuous flow process can be used to make precursors of [1.1.1]propellane.
