Iridium-catalysed regioselective borylation of carboranes via direct B–H activation
Carboranes are carbon-boron molecular clusters, which can be viewed as three-dimensional analogues to benzene. They are finding many applications in medicine, materials and organometallic chemistry. On the other hand, their exceptional thermal and chemical stabilities, as well as 3D structures, make them very difficult to be functionalized, in particular the regioselective functionalization of ...
متن کامل4,5-Bis(4-methoxyphenoxy)phthalonitrile
The title compound, C(22)H(16)N(2)O(4), was obtained unintentionally as the product of an attempted synthesis of a new phthalocyanine. The dihedral angles formed by the central benzene ring with the aromatic rings of the meth-oxy-phen-oxy groups are 85.39 (5) and 64.19 (5)°.
متن کاملOrtho-C-H borylation of benzoate esters with bis(pinacolato)diboron catalyzed by iridium-phosphine complexes.
Iridium complexes generated from [Ir(OMe)(COD)](2) and tris[3,5-bis(trifluoromethyl)phenyl]phosphine efficiently catalyzed the ortho-C-H borylation of benzoate esters with bis(pinacolato)diboron in octane at 80 degrees C to produce the corresponding arylboronates in high yields with excellent regioselectivities.
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اول4,5-Bis(2,4-di-tert-butylphenoxy)phthalonitrile
In the title compound, C(36)H(44)N(2)O(2), the dihedral angles between the phthalonitrile ring and the two di-tert-butyl-benzene rings are 68.134 (8) and 70.637 (11)°. The two nitrile groups are almost coplanar with the phthalonitrile ring except for one of the N atoms which deviates from the plane by 0.125 (4) Å. One of the tert-butyl groups is disordered over two orientations, with refined oc...
