Abstract:
Four Mn(II)-based MIL-53 single crystals were prepared using four neutral pyridine N-oxides as bridging mu(2)-ligands. In the case of 4,4'-bipridine-N,N'-dioxide (BPNO), the infinite manganese oxide chains were further interconnected by BPNO besides BDC, which allows 1D channels to be accessible for guest molecules. The liquid-phase adsorption and separation of C6-C8 aromatics using the evacuated compound as an absorbent were investigated via crystal-to-crystal transformations. Both structural evolution of the compounds and selectivity of C6-C7 aromatics of one evacuated compound could be attributed to noncovalent interactions, especially pi-pi interaction.

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.
