and Lu's reagent 1 a being the most reactive and Billard's reagent 1 h being the least reactive electrophile. While the observed electrophilic reactivities (E) of the amido‐derived trifluoromethylthiolating reagents correlate well with the calculated Gibbs energies for heterolytic cleavage of the X−SCF3 bonds (Tt+DA), the cumol‐derivedreagents 1 f and 1 g are more reactive than expected from the thermodynamics

performed under a traditional batch methodology and under continuousflow conditions. In general, yields obtained using the traditional batch process were higher than those observed when the reaction was performed under flow conditions. However, short reaction times, higher productivity and higher space time yields were observed when a flow system process was employed. Preliminary DFT calculations

α-trifluoromethylthiolation of carbonylcompounds in soft acidic conditions has been developed. With this method only mono-trifluoromethylthiolation was selectively observed. Base-sensitive ketones can then be trifluoromethylthiolated. More sensitive aldehydes are also trifluoromethylthiolated under these conditions with good yields. This work provides a new route towards the synthesis of various valuable t

prefunctionalization, has been developed. Aldehydes, ketones, esters, amides, keto‐esters, alkaloids, and steroids have been trifluoromethylthiolated with good yields. This work, proposing a new reagent for electrophilic trifluoromethylthiolation, provides a route towards the original synthesis of various trifluoromethylthiolated molecules for further applications.

The treatment of bis-(1,2-trimethylsilyloxy)-1-cyclobutene, 1-(1-trimethylsilyloxy)cyclpentene and 1-(1-trimethylsilyloxy)cyclohexene with trifluoromethylsulfenyl chloride has been found to furnish trifluoromethylthiolated carbonyl derivatives.
