Borane‐Catalyzed Water Dehydrogenation at Dioxaphospholes and ‐Phospholanes

open access: yesAngewandte Chemie International Edition, EarlyView.
The borane‐catalyzed dehydrogenation of phenylphosphinate esters, which are formed from the reaction of dioxaphospholes and ‐phospholanes with water or air moisture under mild conditions, is reported. The mechanism of this transformation was investigated by kinetic measurements and DFT calculations, which indicate hydrogen elimination from a ...

Deprotective Alkylation: A Platform for Alcohol‐to‐Amine Interconversion Using Nonafluoromesitylenesulfonamides

open access: yesAngewandte Chemie International Edition, EarlyView.
The straightforward conversion of alcohols to tertiary or secondary amines employing Nms‐amides in a single operation is described. The transformation features broad functional group tolerance and high stereospecificity, underscoring its utility in the synthesis of isotope‐labeled pharmaceuticals.

Transformative Masked Ortho‐Quinone Chemistry: From Direct Guaiacol Activation to Lignin‐Based Adhesives

open access: yesAngewandte Chemie International Edition, EarlyView.
Renewable guaiacols are rapidly oxidized by phenyliodine(III)diacetate to masked ortho‐quinones, giving a new class of monomers that undergo selective Michael‐type polyaddition with multithiols to from thiol‐guaiacol connectivity‐bearing polymers. The activation applies to discrete monomers and directly to lignin, enabling two‐component adhesives that ...
