The reaction of terminal alkynes with perfluoroalkanesulfinyl chlorides was achieved in the presence of n-BuLi/ZnCl2. A series of α-alkynyl perfluoroalkyl sulfoxides were synthesized for the first time in moderate to good yields via the nucleophilic substitution reaction of alkynylzinc chlorides formed in situ with perfluoroalkanesulfinyl chlorides.

A monodentate directinggroup, 2-chlorotetrafluoroethylsulfinylmide (-NHSOCF2CF2Cl), for inert C(sp3)–H bond activation is reported. This directinggroup shows efficient ability in Pd(II)-catalyzed C(sp3)–H olefination. The desired olefination products undergo subsequent Michael addition and in situ expulsion of the auxiliary to provide the free NH γ-lactam products. Preliminary mechanistic studies

protocols were reported for the synthesis of a wide range of polyfluoroalkanesulfinyl or alkylsulfinyl 4-isoxazolines. A variety of aldehyde and ketone derived nitrones reacted with α-alkynyl sulfoxides under catalyst- and solvent-freeconditions at roomtemperature to provide a series of polyfluoroalkanesulfinyl or alkylsulfinyl 4-isoxazolines with high efficiency. The synthesis of these sulfinyl 4-isoxazolines

A facile method for the trifluoromethylsulfinylation of activatedarenes with trifluoromethanesulfinyl chloride in the presence of Lewis acid was developed. The protocol could be expanded to the perfluoroalkylsulfinylation of activatedarenes, as well as the trifluoromethylsulfinylation of indoles without additive.

日期:2009.3
The addition reaction of perfluoroalkanesulfinyl chlorides to alkoxyallenes was achieved under mild conditions. Two kinds of perfluoroalkyl alkenyl sulfoxides, beta-alkoxyvinyl perfluoroalkyl sulfoxides and alpha-perfluoroalkanesulfinyl enones or enals, were obtained selectively depending on the structure of alkoxyallenes.
