Phenyl Groups Result in the Highest Benzene Storage and Most Efficient Desulfurization in a Series of Isostructural Metal-Organic Frameworks

A series of isoreticular metal-organic frameworks (MOFs; NENU-511-NENU-514), which all have high surface areas and strong adsorption capacities, have been successfully constructed by using mixed ligands. NENU-513 has the highest benzene capacity of 1687 m

Efficient one pot preparation of variously substituted thieno[2,3-b]thiophene

An efficient one pot access to variously substituted thieno[2,3-b]thiophene is described. The title compounds were obtained from 1,3-dicarbonyl or equivalent compounds, carbon disulfide and halomethyl derivatives in good to high yields and fully characterized.

SYNTHESIS OF THIENO(2,3-b)THIOPHENES AND RELATED STRUCTURES

Some new functionally substituted thieno(2,3-b)thiophenes and related compounds were obtained in a one-pot reaction using phase transfer catalysis conditions starting with some active nitriles or active methylene compounds, carbon disulphide or phenyl isothiocyanate and α-chlorocarbethoxy, or α-nitrile electrophiles.The structure of the obtained new compounds was assigned.Key words: Thiophene; thienothiophene; dithiolane; thiazolidinone; thiazoline; thienopyrazole; furopyrazole.
