Facile Arylation of Four-Coordinate Boron Halides by Borenium Cation Mediated Boro-desilylation and -destannylation

The addition of AlCl3 to four-coordinate boranes of the general formula (C-N-chelate)BCl2 results in halide abstraction and formation of three-coordinate borenium cations of the general formula [(C-N-chelate)BCl]+. The latter react with both arylstannanes and arylsilanes by boro-destannylation and -desilylation, respectively, to form arylated boranes. Catalytic quantities of AlCl3 were sufficie...

A four-coordinate Fe(III) porphyrin cation.

Few families of compounds have been as intensely studied as iron porphyrin complexes. In spite of this, a truly four-coordinate Fe(III) porphyrin cation has never before been reported.1 The exceptional electrophilicity of the four-coordinate [FeIII(Porph)]+ cation will even coordinate arene solvent upon crystallization if the counteranion is extremely non-coordinating, as in the work of Reed wi...

Facile synthesis of hypersilylated aromatic compounds by palladium-mediated arylation reaction.

The treatment of aryl iodides with tris(trimethylsilyl)silane in the presence of Pd(P(tBu)(3))(2) and the Hünig base leads to the formation of hypersilylated aromatic products in good to excellent yields without cleavage of weak Si-Si bonds under mild conditions.

Copper-mediated arylation with arylboronic acids: Facile and modular synthesis of triarylmethanes

A facile and modular synthesis of triarylmethanes was achieved in good yield via a two-step sequence in which the final step is the copper(II)-catalyzed arylation of diarylmethanols with arylboronic acids. By using this protocol a variety of symmetrical and unsymmetrical triarylmethanes were synthesized. As an application of the newly developed methodology, we demonstrate a high-yielding synthe...

Efficient iron-catalyzed N-arylation of aryl halides with amines.

A practical and promising protocol was developed for N-arylations of various amines with differently substituted aryl halides. The processes are efficiently promoted by the catalyst system involving the environmentally benign Fe2O3 and the universal ligand L-proline. The versatility, convenient operation, low cost, and environmental friendliness, in combination with the high yields, render this...
