Syntheses and Properties of Pentafluoroethylplumbanes in the Oxidation States +II, +III, and +IV

Chemistry – A European Journal, EarlyView.
Syntheses of pentafluoroethyl substituted plumbanes in the formal oxidation states +II, +III, and +IV are reported. The compounds were characterized by multinuclear NMR spectroscopy, including 207Pb NMR spectroscopy, mass spectrometry and single‐crystal x‐ray diffraction experiments. ABSTRACT Mono‐, bis‐, and tris(pentafluoroethyl)plumbanes of the type

Regioselective Aldol Reactions Directed by Charge and Orbital Effects in Cyclic Germyl Dienolates: Synthesis of Three Distinct Regio‐ and Stereoisomers

Chemistry – A European Journal, EarlyView.
Charge and orbital control represent fundamental principles in organic chemistry. In this study, these principles are applied to the aldol reactions of a cyclic Ge‐dienolate. By systematically tuning the charge and orbital distributions of the Ge‐dienolates and their aldehyde reaction partners, regio‐ and stereoselective access to three distinct aldol ...

The Mechanism of Visible‐Light Photochemical Rearrangements of Conjugated Amide Enolates

Chemistry – A European Journal, EarlyView.
Visible light irradiation of extended enolates of N‐benzylamides leads to homolytic C─N Bond cleavage, generating a biradical. Computational and mechanistic studies suggest rapid radical recombination within a solvent cage to give either ring‐expanded or rearranged products. ABSTRACT Deprotonation of conjugated amides forms colored solutions of lithium

N‐Sulfonyl Azalevoglucosan: A Versatile Platform for the Synthesis of Polysubstituted Piperidines

Chemistry – A European Journal, EarlyView.
Gain by strain: The synthesis of a levoglucosan analog, in which the pyranose oxygen has been replaced by a nitrogen, allows navigation on the piperidine ring to iteratively install functional groups at C1, C2, C3, C4, and C6 positions using simple experimental protocols with minimal protecting group manipulation.
