The nucleophilic trichloromethylation of fluoroketones was carried out by the reductive addition of CCl4 in the presence of aluminum or by the reaction of trichloroacetic acid in HMPTA. The trichloromethylcarbinols obtained were used in the synthesis of perfluorinated tertiary alcohols and trifluoromethylated 1,1-dichlorooxiranes.

Described herein are compounds, pesticidally acceptable salts thereof, and compositions thereof that are useful, for example, for pest management and for controlling pests. In certain embodiments provided are enantioenriched and/or enantiopure compounds and pesticidally acceptable salts thereof, and methods of making same. Methods of controlling pests with the compounds of the disclosure are also provided.
Synthetic application of 3,3-dichloro-1,1,1-trifluoroacetone (DCTFA) and 3,3,3-trichloro-1,1,1-trifluoroacetone (TCTFA) for trifluorolactic acid derivatives
the other hand, α-substituted trifluorolactic acid derivatives, such as α-methyltrifluorolactic acid and Mosher’s acid, were obtained by addition reaction between TCTFA and carbon nucleophiles, followed by subsequent transformation of trichloromethylgroup.
