Fig. 3: Synthesis of cholorcyclopropyl ketone 70. Alkylacylation using chloroform as alkyl halide gave chloorocyclopropyl ketone as the final product. Full size image Fig. 4: Cascade alkylacylation/cyclopropanation. Reaction conditions:1m(0.20 mmol),2(0.40 mmol),3w(2.0 mmol) or3x(1....
In primary alkyl halides, the carbon bonded to the halogen atom is directly bonded to only one other carbon. An example of this is bromoethane, which has the chemical formula {eq}CH_3CH_2Br {/eq}. In a secondary alkyl halide, the carbon that is bonded to the halogen atom is bonded ...

21a They can, however, be converted to the corresponding vinylcopper compounds by treatment with another equivalent of copper(I) halide prior to the addition of the alkynyl halide substrate, an advantageous procedure in light of the ready availability of divinylcuprates by carbocupration of alkynes...
obtained when a novel tertiary amine is used, by previously subjecting a tertiary amine recovered from reaction system to dehydration treatment using a compound decomposable by reacting with water such as carboxylic anhydride and using the treated tertiary amine in reaction with an aliphatic halide. ...
Condensation of alkyl ketones in presence of aqueous ammonium halide solutionsSerial No. 542,804 12 Claims. (Cl. 260-668) 12 This invention relates to a process for treating an alkyl ketone with a particular catalytic material. More specifically, the invention is concerned with a process for ...
Reductive amination using stoichiometric amounts of sodium triacetoxyborohydride (NaBH(OAc)3) proves to be a group-tolerant method for amine synthesis30. However, when the ketone or aldehyde reagents contain a keto or alkyl halide functional group, the amination is unsuccessful (Fig. 6e,f). On...
