Szupiluk, Artur published the artcileSynthesis of sterically crowded 9-nitrotriptycenes by the Diels-Alder cycloaddition reaction, SDS of cas: 3032-32-4, the main research area is nitroanthracene halobenzyne regioselective Diels Alder reaction; nitrotriptycene preparation.
The synthesis of novel sterically crowded triptycenes as attractive components for the construction of models for various mol. dynamic studies was reported. 9-Nitrotriptycenes were obtained by the Diels-Alder reactions between 9-nitroanthracene and tetrabromobenzyne as well as 1,4-dichloro-9-nitroanthracene and 2,6-dichlorobenzyne. Interesting regioselectivity relative to the central and terminal rings was observed Moreover, 1,2,3,4-tetrabromo-9-nitrotriptycene was further functionalized to afford 1,2,3,4-tetrabromotriptycyl-9-ammonium tetrafluoroborate in two-steps. The impact of steric hindrance on the geometry of the mol. was estimated on the basis of single crystal X-ray diffraction data.
Tetrahedron Letters published new progress about Diels-Alder reaction, regioselective. 3032-32-4 belongs to class chlorides-buliding-blocks, name is 2-Amino-3,6-dichlorobenzoic acid, and the molecular formula is C7H5Cl2NO2, SDS of cas: 3032-32-4.
