Alkyl Bismuth Cations: Synthesis, Characterization, and Application as Z‐Type Ligands
Chemistry – A European Journal, EarlyView.Rare examples of alkyl bismuth cations [BiR2(SbF6)] are presented, including cyclopropyl ligands and a bismacyclic structure. The bismuth‐centered Lewis acids act as Z‐type ligands toward the electron‐rich platinum atom in [Pt(PCy3)2], generating a set of metal‐only Lewis pairs. The structural and spectroscopic properties of these rare types of bismuth

Masked Silylenes: Controlled Generation and Reactivity Under Thermal and Equilibrium Conditions
European Journal of Inorganic Chemistry, EarlyView.This Review provides an overview of masked silylenes as bench‐stable precursors that release silylenes (R2Si:) under thermal activation or reversible equilibria. Precursor preparation, generation pathways, and characteristic reactivity are summarized, including trapping chemistry, reversible interconversions, insertion‐type processes, and small ...

Isocyanide-based multicomponent reactions towards cyclic constrained peptidomimetics
Beilstein Journal of Organic Chemistry, 2014 In the recent past, the design and synthesis of peptide mimics (peptidomimetics) has received much attention. This because they have shown in many cases enhanced pharmacological properties over their natural peptide analogues.

European Journal of Organic Chemistry, EarlyView.The one‐pot synthesis of 3‐benzylidenbenzo[c]thiophen‐1‐amines was achieved through the nickel‐catalyzed three‐component coupling reaction of 1‐ethynyl‐2‐iodobenzenes, tert‐butyl isocyanide, and hexamethyldisilathiane. This procedure is applicable to the preparation of secondary thioamides using aryl iodides.
