Hydrolytic cleavage of both CS2 carbon–sulfur bonds by multinuclear Pd(II) complexes #chempaperaday 284

C-S activation is as important as C-O activation. There are sulfur containing compounds (impurities) in petroleum products and separating them from the desired product is not as easy as it may seem. These sulfur containing products can "poison" catalysts and also have some not so desired affects on the environment. Although not as common as CO2 activation, you occasionally see some CS2 activation. But, cleaving both C-S bonds in CS2 has not been seen. Well, until now. Here the authors use a Pd complex that also exists as a dimer in solution to cleave these bonds. Moreover, they were able to convert CS2 into CO2 and SO2 through really cool mechanisms (proposed). VERY COOL chemistry.
