Abstract:
In the mononuclear title compound, [Ni(CH(3)COO)(2)(C(6)H(6)N(2)O)(2)], the Ni(II) atom is coordinated by two pyridine-2-aldoxime (PaoH) ligands and two acetate groups, with cis coordination for the pairs of identical ligands. While each acetate group binds to the Ni(II) atom by one O atom, each PaoH chelates the Ni(II) atom through two N atoms. The O atom on PaoH is not deprotonated and does not participate in bonding to the Ni(II) atom. Thus, the Ni(II) atom exhibits an octa-hedral environment. Intra-molecular O-H⋯O hydrogen-bonding inter-actions and inter-molecular C-H⋯O hydrogen-bonding inter-actions are present in the structure. Adjacent mol-ecules pack along [100] through van der Waals forces.

Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
Oxidations of Aldehydes and Ketones to Carboxylic Acids
Aldehydes readily undergo oxidation in strong oxidizing agents such as potassium permanganate and chromic acid. The oxidation can also be carried out using mild oxidizing agents such as silver oxide. In fact, aldehydes can be easily oxidized...
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
