Special Issue Information

Dear Colleagues,

There can be no doubt that we are living in the golden age of boron chemistry.  It is difficult to go through any journal these days without seeing at least a half a dozen articles dedicated to the latest developments in organoboron chemistry.   Metal catalyzed borylations, including the Suzuki-Miyaura cross-coupling reaction, are effective, general and non-toxic routes to preparing a wide array of novel organic compounds.  Sterically congested boron compounds have recently found applications in Frustrated Lewis Pair (FLP) chemistry and new applications to these remarkable species are becoming more and more common.  Organoboron compounds are also making significant headway in medicinal chemistry, as either stalwart synthons or as biologically active materials.  Discrete molecules and polymers containing three-coordinate boron atoms exhibit a number of amazing physicochemical properties that are finding applications in all areas of science and innovation.
This special issue of Molecules welcomes manuscripts covering all aspects of organoboron chemistry including their design, development and applications.

Palladium-catalyzed alkynylation has emerged as one of the most reliable methods for the synthesis of alkynes which are often used in natural product syntheses and material science. An efficient method for coupling alkynyltrifluoroborates with various aryl bromides in the presence of a palladium catalyst has been developed using microwave irradiation. The microwave reactions are rapid and efficient. Full article

Abstract
A new bidentate phosphoramidite (N-Me-BIPAM) based on Shibasaki’s N-linked BINOL was synthesized.

A new bidentate phosphoramidite (N-Me-BIPAM) based on Shibasaki’s N-linked BINOL was synthesized. This ligand appears to be highly effective for rhodium-catalyzed asymmetric conjugated addition of arylboronic acids to α,β-unsaturated enones. The reaction of ortho-substituted arylboronic acid with acyclic and cyclic enones provides the corresponding products in good yields and enantioselectivities. Full article
