Perhaloalkanesulfenyl chlorides are reacted with aldehydes and ketones to provide novel (perhaloalkyl)thio-substituted aldehydes and ketones which are useful organic solvents and intermediates. As intermediates, these compounds are especially useful in the preparation of their carbamate derivatives which have pesticical utility.
metal‐free protocol for the domino trifluoromethylthiolation/decarboxylation of β‐ketocarboxylic acids is described. The catalytic reactions take place in acetonitrile in the presence of aqueous ammonium hydroxide and N‐trifluoromethylthiosaccharin. The sequence of events and reaction mechanism were established experimentally and using density functional theory calculations. This synthetic method offers a convenient
