1,3‐Brook Rearrangement of α‐Silyl Allylic Alcohols: Copper‐Catalyzed Enantiospecific Formation of Allenes and Copper‐Mediated ipso‐Substitution Reactions Affording Trisubstituted Alkenes

Angewandte Chemie, EarlyView.
A regioselective ruthenium catalyzed trans‐hydrosilylation of propargyl alcohols followed by a 1,3‐Brook rearrangement opens access to reactive organocopper intermediates, which evolve upon warming into allenes with strict chirality transfer to the emerging axis; alternatively, these reactive species can be trapped with a large variety of electrophiles

Ring‐Retentive Allylation of Cyclopropanols Through Interception of Enolized Homoenolates by π‐Allylpalladium

Angewandte Chemie, EarlyView.
Cyclopropanols undergo palladium‐catalyzed, zinc‐mediated allylation with allyl acetates: the ring opens transiently to an enolized homoenolate, is intercepted by π‐allylpalladium, and recloses to furnish β‐allylated cyclopropanols. This formal “allylic cyclopropylation” broadens the reaction space for ring‐retentive functionalization of cyclopropanols.

Luminescence Vapochromism of a Cu(I)/Na Phosphane Iodide Assembly Based on a Secondary‐Sphere Sodium Response

Angewandte Chemie, EarlyView.
The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.
