Hydroboration of Carbon Disulfide with Sodium Tetrahydridoborate. Pentasodium Tetrakis (dithiomethylene) borate, a Salt with a New “Tetrathioborate” AnionCarbon disulfide reacts in THF, acetonitrile, or N, N-dimethylthioformamide with NaBH4 to give pentasodium tetrakis(dithiomethylene) borate, 6. The reaction mechanism for the new anion [B⊖(S—CH2—S⊖)4] can be described by stepwise CS2 insertion to the B—H bonds of BH4⊖ and H⊖ transfer from BH4⊖ to the intermediates. The results of these reactions have been obtained by 1H and 11B NMR spectroscopy.
Notes:
Kohlenstoffdisulfid reagiert in THF, Acetonitril oder N,N-Dimethylthioformamid mit NaBH1 zu Pentanatrium-tetrakis(dithiomethylen)borat, 6. Die Bildung des neuen Anions [B⊖ (S—CH2—S⊖)4] erfolgt durch schrittweise CS2-Insertion in die B—H-Bindungen des BH4⊖-Ions sowie durch H⊖-Übertragung von BH4⊖ auf die Zwischenprodukte. Die 1H- und 11B-NMR-Spektren werden diskutiert.
