Investigation of redox switchable titanium and zirconium catalysts for the ring opening polymerization of cyclic esters and epoxides

The synthesis and characterization of (thiolfan*)Zr(OtBu)2 (thiolfan* = 1,1′-di(2,4-di-tert-butyl-6-thiophenoxide)ferrocene) is reported, as well as its activity toward the ring-opening polymerizations of L-lactide and ε-caprolactone.

Palladium complexes of ferrocene-based phosphine ligands as redox-switchable catalysts in Buchwald–Hartwig cross-coupling reactions

Redox-switchable catalysis: Palladium(II) complexes of two differently substituted [1]phosphaferrocenophanes FcPR (R = Mes, biaryl) and of diphenylferrocenyl phosphine Ph2PFc were applied in redox-switchable Buchwald–Hartwig cross-coupling reactions.

Redox control in palladium catalyzed norbornene and alkyne polymerization

Switchable polymerization of norbornene, 5-norbornene-2-yl acetate and 1-chloro-1-octyne could be realized by using two palladium complexes (NHC)Pd(allyl)Cl (NHC = 1,3-Ar2-naphthoquinimidazolylidene, Ar = 2,6-Me2-C6H3, 2,6-iPr2-C6H3) bearing a redox-active naphthoquinone moiety.

About this collection

InorgChemFront is delighted to publish a collection of articles on “Switchable Catalysis and Related Reactions”, guest edited by Paula Diaconescu (University of California, Los Angeles) and Jeffery Byers (Boston College).

Switchable catalysis is an atom-economical method that generates multiple, catalytically active species with different reactivity. It regulates by external stimuli the catalytic process both temporally and spatially. This emerging field of catalysis research enjoys more popularity than ever because it enables a complete control over selectivity of a range of chemical transformations and also accomplishes fast production of molecular complexity for efficient chemical synthesis. In recent years, utility of switchable catalysts and related reactions have also started to be explored in a broader field, such as materials or energy related areas.

Some of the recent important progresses in switchable catalysis and stimuli-responsive systems will be highlighted in this themed collection. More articles will be added as soon as they have been published.
