The boron–boron triple bond in NHC→BB←NHC
Quantum chemical calculations of the compound B2(NHC )2 and a thorough examination of the electronic structure with an energy decomposition analysis provide strong evidence for the appearance of boron–boron triple bond character. This holds for the model compound and for the isolated diboryne B2(NHC )2 of Braunschweig which has an even slightly shorter B–B bond. The bonding situation in the mol...
متن کاملModulating NHC catalysis with fluorine
Fluorination often confers a range of advantages in modulating the conformation and reactivity of small molecule organocatalysts. By strategically introducing fluorine substituents, as part of a β-fluoroamine motif, in a triazolium pre-catalyst, it was possible to modulate the behaviour of the corresponding N-heterocyclic carbene (NHC) with minimal steric alterations to the catalyst core. In th...
متن کاملGold and Platinum Catalysis of Enyne Cycloisomerization
This account provides a comprehensive overview of the development of gold and platinum catalysis of the enyne cycloisomerization. The use of these soft, alkynophilic metals enables mild, chemoselective and efficient transformations of a variety of readily available acyclic enynes to a wide range of synthetically useful carbocyclic and heterocyclic products. The review is organized according to ...
متن کاملCascade radical reaction of substrates with a carbon–carbon triple bond as a radical acceptor
The limitation of hydroxamate ester as a chiral Lewis acid coordination moiety was first shown in an intermolecular reaction involving a radical addition and sequential allylation processes. Next, the effect of hydroxamate ester was studied in the cascade addition-cyclization-trapping reaction of substrates with a carbon-carbon triple bond as a radical acceptor. When substrates with a methacryl...
متن کاملEnyne metathesis (enyne bond reorganization).
Enyne metathesis is a bond reorganization of an alkene and an alkyne to produce a 1,3-diene (eqs 1 and 2 in Scheme 1). It has been used in both intramolecular and intermolecular applications. Enyne metathesis bears a mechanistic kinship to alkene metathesis; however, it is less-studied than alkene metathesis. The enyne bond reorganization is atom economical and is driven by the enthalpic stabil...
