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.

Catalysis
Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...
Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
