The title compound, C64H66B4N4O8·2C6H5NO2, is a nitro-benzene solvate of a meso-tetra-phenyl-porphyrin species with unconventional peripheral boronic ester substituents. The porphyrin units reside in the crystal on centers of inversion and exhibit a chann
C-H activation by amide chelation control: Ruthenium-catalyzed direct synthesis of 2-Aryl-3-furanamides

A new, catalytic methodology for the synthesis of heterobiaryls by the ruthenium-catalyzed C-H activation/cross-coupling of heterocyclic amides with aryl boroneopentylates is surveyed. From this survey, the highly regioselective reaction of furan-3-carboxamide to give 2-aryl-3-furanamides is optimized and generalized in scope with respect to the aryl boroneopentylate coupling partners. Established thereby is a one-step synthetic method which may supercede the broadly applied two-step directed ortho metalation (DoM)-cross coupling reaction involving cryogenic and strong base conditions and which has potential for further ortho and remote metalation chemistry.
Borylation of organo halides and triflates using tetrakis(dimethylamino) diboron

We report a new in situ borylation method using tetrakis(dimethylamino) diboron, DMA4B2, in the presence of a diol. Our method uses standard borylation conditions and readily available Pd-catalysts. The scope of this method includes aryl halides and triflates as well as vinyl halides and triflates. The method successfully works with a broad range of diols, enabling the selection of the best boronic ester for subsequent Suzuki coupling.
