Mechanochemical Approach for Metal‐Free Regioselective C5‐Sulfenylation of Imidazo[2,1‐b]Thiazoles

open access: yesChemSusChem, EarlyView.
This study presents a mechanochemical approach for the metal‐free, regioselective C5‐sulfenylation of imidazo[2,1‐b]thiazoles using bis(trifluoroacetoxy)iodo]benzene and aryl methyl sulfides. The method, performed under solvent‐free ball‐milling conditions, provides an efficient, environmentally friendly alternative to conventional synthesis, achieving

Phosphanyl‐Substituted Tetrylenes and Ditetrelenes: Impact of Steric Bulk on Tetrylene/Ditetrelene Stability

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The use of the intermediately bulky phosphanyl substituent (2,4,6‐Et3C6H2)2P [(Tep)2P] enables the isolation of a highly twisted and trans‐bent digermene {(Tep)2P}2GeGe{P(Tep)2}2, which undergoes a digermene‐germylene equilibrium in solution. While the corresponding stannylene/distannene could not be isolated, the analogous compound {(Dep)2P}2Sn (Dep =

Boron‐Boron Single Bonds Mimicking Transition Metals

open access: yesEuropean Journal of Inorganic Chemistry, Accepted Article.
This review article deals with a special transition‐metal like reactivity of ambiphilic (electrophilic and nucleophilic) diborane molecules with a B‐B single bond, namely the ability to coordinate a substrate and reduce it in their coordination sphere with the electrons from the B‐B bond.

Molecular iodine‐mediated functionalization of α‐Carbonyl Sulfoxonium ylides with Thiocyanates, Xanthates and Dithiocarbamates

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
In this work, we present a straightforward, rapid, and cost‐effective protocol for synthesizing three distinct classes of α‐functionalized sulfoxonium ylides—α‐xanthate, α‐thiocyanate, and α‐dithiocarbamate—via molecular iodine‐mediated reactions. This method demonstrates broad substrate tolerance, including heterocycles and steroids, delivering 25 ...
