Abstract:
The synthesis of graphyne has been considered challenging, especially when it comes to adopting new topologies and obtaining thinner layers. Herein, we report the synthesis and characterization of a graphyne-like porous carbon-rich network via alkyne metathesis reactions, which resulted in a sp2/sp hybridized 2D thin film structure with a layer to layer distance of 0.37 nm. This graphyne-like porous carbon-rich network is an n-type semiconductor with a low work function of 3.9 eV and a reduction potential of -0.54 V vs. SHE, which could be applied as an excellent reducing agent for metal electroless deposition. In addition, this material has a narrow pore size distribution of 2 to 4 nm, a high surface area of 675 m2 g-1 and a large pore volume of 0.795 cm3 g-1 favoring gas adsorption. It shows the selective absorption of CO2 over N2 owing to the strong affinity between CO2 and the carbon-carbon triple bond.

Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.
Preparation of Alkynes: Dehydrohalogenation
Alkynes can be prepared by dehydrohalogenation of vicinal or geminal dihalides in the presence of a strong base like sodium amide in liquid ammonia. The reaction proceeds with the loss of two equivalents of hydrogen halide (HX) via two successive E2 elimination reactions.
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.
Alkynes to Aldehydes and Ketones: Acid-Catalyzed Hydration
Analogous to alkenes, alkynes also undergo acid-catalyzed hydration. While the addition of water to an alkene gives an alcohol, hydration of alkynes produces different products such as aldehydes and ketones.
