V. Dodincarnot et al., REACTIVITY OF DITHIOPHOSPHORIC ACID TOWARDS SULFURATED MONOSUBSTITUTED ALKYNES IN PRESENCE OF TRANSITION-METAL-CATALYST, Phosphorus, sulfur and silicon and the related elements, 117, 1996, pp. 225-230
The reactivity of sulfurated monosubstituted alkynes with dithiophosph
oric acid (noted Z-H) has been investigated. Depending on the transiti
on-metal-catalyst (Ni, Pd, Rh) and solvent (benzene or THF), two types
of alkenes can be isolated: Z-CH=CH-CH2-SR and/or Z-C(CH2-SR)=CH2. Th
e selectivity of this reaction was studied. C-13 and P-31 NMR of these
new sulfurated alkenes are reported.
