Organocatalyzed Anodic Oxidation of Aldehydes
A method for the catalytic formation of electroauxiliaries
and
subsequent anodic oxidation has been developed. The process interfaces
N-heterocyclic carbene-based organocatalysis with electro-organic
synthesis to achieve direct oxidation of catalytically generated electroactive
intermediates. We demonstrate the applicability of this method as
a one-pot conversion of aldehydes to esters for a broad range of aldehyde
and alcohol substrates. Furthermore, the anodic oxidation reactions
are very clean, producing only H<sub>2</sub> gas as a result of cathodic
reduction
Expanded Functionality of Polymers Prepared Using Metal-Free Ring-Opening Metathesis Polymerization
Photoredox-mediated
metal-free ring-opening metathesis polymerization
(MF-ROMP) is an alternative to traditional metal-mediated ROMP that
avoids the use of transition metal initiators while also enabling
temporal control over the polymerization. Herein, we explore the effect
of various additives on the success of the polymerization in order
to optimize reaction protocols and identify new functionalized monomers
that can be utilized in MF-ROMP. The use of protected alcohol monomers
allows for homo- and copolymers to be prepared that contain functionality
beyond simple alkyl groups. Several other functional groups are also
tolerated to varying degrees and offer insight into future directions
for expansion of monomer scope
