Usage

General Description

Dimesitylmethane is a chemical compound with the formula CH2(C6H2Me3)2. It's an aromatic hydrocarbon in which the two mesityl groups attached to a single carbon atom in a methane molecule. It is known for its stability and resistance to oxidation. Dimesitylmethane is produced from the corresponding lithium salt via acidification. It is mostly used as a laboratory reagent due to its highly sterically hindered methylene group. Furthermore, it exhibits resonance stabilization which contributes to its overall unreactivity, and it can act as a strong ligand in metal complexes.

Development of Versatile Sulfone Electrophiles for Suzuki-Miyaura Cross-Coupling Reactions

The development of fluorinated sulfone derivatives as versatile electrophiles for Suzuki-Miyaura cross-coupling reactions is described. Introducing electron-withdrawing groups on the aryl ring of the sulfone facilitates the Pd-catalyzed activation of C-SO2 bonds. Cross-coupling reactions with fluorinated sulfone electrophiles are reported, leading to a variety of multiply arylated products in good yields. The reactivity of this unusual electrophile is benchmarked versus common electrophiles and its use in iterative cross-couplings for concise synthesis of biologically active molecules is described.

A tubular europium-organic framework exhibiting selective sensing of Fe3+ and Al3+ over mixed metal ions

A luminescent europium-organic framework with tubular channels based on the H4BTMIPA ligand (H4BTMIPA = 5,5′-methylenebis(2,4, 6-trimethylisophthalic acid)) was assembled and characterized. The [H 2N(CH3)2]+ ions as counterions are located in the channels. The cation exchange between [H2N(CH 3)2]+ and metal ions resulted in complex 1 that can selectively sense Fe3+ and Al3+ ions through fluorescence quenching and enhancement, respectively.

Phase transfer catalyst supported, room-temperature biphasic synthesis: A facile approach to the synthesis of coordination polymers

A facile approach, named phase transfer catalyst supported, room temperature biphasic synthesis, has been developed to synthesize a new type of coordination polymers. Compared to the traditional biphasic solvothermal synthesis that was run at high temperature (100-200 °C), the new approach introduced here can be operated under a mild condition (room temperature) with the support of phase transfer catalyst. With the application of this new approach, two copper coordination complexes with 1D metal-organic nanotube and 1D coordination polymer containing large water clusters have been successfully synthesized and characterized. Furthermore, the synthetic approach presented here can be extended to synthesize other coordination polymers, including porous lanthanide-organic frameworks.
