Elemental sulfur reacts with primary phosphines and various amines in the 3:1:2 molar ratio under mild conditions (60°C, 10 min, ethanol) to afford hitherto unknown organylammonium trithiophosphonates in 84–91% yields.

The complex (NHC)2Sm[N(SiMe3)2]2 (NHC = 1,3-diisopropyl-2H-imidazole-2-ylidene) (5Sm) proved to be the most efficientcatalyst, which enabled hardly realizable transformations such as PhPH2 addition across internal C═C bonds of norbornene and cis- and trans-stilbenes, providing the highest reaction rate for addition of PH3 to styrene. Excellent regio- and chemoselectivities of alkylation of PH3 with
