Copper-mediated (phenylsulfonyl)difluoromethylation of propargyl chlorides and alkynyl halides with PhSO2CF2TMS reagent was successfully achieved to give PhSO2CF2-containing allenes and alkynes, respectively. It is believed that the in situ formed PhSO2CF2Cu species is involved in the present (phenylsulfonyl)difluoromethylation reactions.

Anisole and fluoroanisoles display distinct conformational preferences, as evident from a survey of their crystal structures. In addition to altering the free ligand conformation, various degrees of fluorination have a strong impact on physicochemical and pharmacokinetic properties. Analysis of anisole and fluoroanisole matched molecular pairs in the Pfizer corporate database reveals interesting trends:
