IMPROVED PROCESS FOR THE PREPARATION OF A BENZENE COMPOUND

A benzene compound is prepared in a process, which comprises (i) reacting a furan compound of formula (I): wherein R1 and R2 are the same or different and independently selected from the group consisting of hydrogen, alkyl, aralkyl, -CHO, -CH2OR3, -CH(OR4 )(OR5), -COOR6, wherein R3, R4 and R5 are the same or different and are independently selected from the group consisting of hydrogen, alkyl, aryl, alkaryl, aralkyl, alkylcarbonyl and arylcarbonyl, or wherein R4 and R5 together form an alkylene group, and wherein R6 is selected from the group consisting of hydrogen, alkyl and aryl, with an olefin of the formula (II): R7-CH=CH-R8; wherein R7 and R8 are the same or different and are independently selected from the group consisting of hydrogen, sulfonate, -CN, -CHO, and -COOR9, wherein R9 is selected from the group consisting of hydrogen, and an alkyl group, or R7 and R8 together form a –C(O)-O-(O)C- group or a –C(O)-NR10-C(O)- group, wherein R10 represents hydrogen, an aliphatic or an aromatic group, to produce an unsaturated bicyclic ether having an unsaturated carbon-carbon bond; (ii) hydrogenating the unsaturated carbon-carbon bond in the unsaturated bicyclic ether to produce a saturated bicyclic ether; and (iii) dehydrating and aromatizing the saturated bicyclic ether to produce the benzene compound.

Triptycene based luminescent metal-organic gels for chemosensing

We report a novel luminescent Al-based metal-organic gel G1 comprising 1,4,5,8-triptycenetetracarboxylic acid, which exhibits highly sensitive detection towards nitro aromatic compounds particularly picric acid. Furthermore, under identical reaction conditions, using a Co(ii) salt instead, a novel 3D framework material, trip-MOF-1, was isolated and its sensitivity towards picric acid was also evaluated.

Synthesis and crystal structures of 1,4,8,11-Tetraalkyl-6,13- diphenylpentacenes

Two 1,4,8,11-tetraalkyl-6,13-diphenylpentacenes were prepared. X-ray analysis revealed that the methyl derivative had a herringbone arrangement with π-overlap, while the propyl derivative had a slipped-parallel structure without π-overlap. The solid-state
