N-phosphanylsulfinamide (PNSO) ligands with electron-deficient sulfinylgroups was synthesized. Reaction with Co2–alkyne complexes yields P,S-bridged complexes. These complexes were used to study the metalbonding of different sulfinylgroups. IR spectroscopy, X-ray analysis, and Pauson–Khand reactivity studies indicated that electrondeficient sulfinylgroups provide enhanced S metalbonding.

The monoreduction of trifluoromethanesulfonyl chloride by an appropriate phosphine, preferentially tricyclohexylphosphine, generates the reactive trifluoromethanesulfinyl chloride CF3SOCl as donor of CF3S(O)+ cation. The direct trifluoromethylsulfinylation of indoles, pyrroles, other azaarenes, amines, and phenols was successfully achieved in moderate to high yields.

An efficient, mild, transition-metal-free method has been developed for the intermolecular C-N sigma-bond addition of amides and S-N sigma-bond addition of sulfinamides to arynes to form one C-C bond and one heteroatom-carbon bond in one step at room temperature. Evidence for a stepwise mechanism is provided.
