title: Reduction of CO2 and SO2 with low valent nickel compounds under mild conditions.
abstract: The reaction of [(dippe)Ni(μ-H)](2) (A) (dippe = 1,2-bis(diisopropyl-phosphinoethane) with CO(2) in toluene afforded the carbonyl nickel(0) compounds of the type {(dippe)Ni(CO)](2)(μ-dippe)}(1) and (dippe)Ni(CO)(dippe==O)] (2), which were characterized by standard spectroscopic methods; complex (1) was also characterized by single crystal X-ray diffraction. Reaction of (A) with SO(2) yields the thiosulfate nickel(II) compound [Ni(dippe)(S(2)O(3))] (5), which was fully characterized by standard spectroscopic methods and X-ray crystallography. In both cases, a reduction reaction of CO(2) to CO and SO(2) to S(2)O(3)(2-) with (A) took place under mild conditions.
