A novel route to dithiolenes from 1,3-dithiole-2-thiones at a dicobalt centre

摘要

On reaction with [Co_2(#mu#-dppm)(CO)_6] at room temperature, 4,5-bis(alkoxycarbonyl)-1,3-dithiole-2-thiones are dismantled into dithiolene and thiocarbonyl ligands by cleavage of two C-S bonds to give [Co_2(#mu#-CS)(#mu#-S_2C_2R_2)(CO)_3(#mu#-dppm)] (R = CO_2Me, CO_2Et).
