Attractive aerobic access to the α,β-unsaturated acyl azolium intermediate: oxidative NHC catalysis via multistep electron transfer [PDF]
, 2016 To replace high molecular weight oxidants with air (O2) we introduce multistep electron transfer NHC catalysis. The method provides a general and selective oxidation of the α,β-unsaturated aldehyde derived homoenolate to the synthetically useful α,β ...

Esters of Cinnamic Acid as Green Plasticizers for Polylactide Formulations with Improved Ductility
Macromolecular Materials and Engineering, 2023 This study demonstrates the potential of different cinnamate esters, namely methyl trans‐cinnamate (MC), isobutyl cinnamate (IBC), allyl cinnamate (AC), and ethyl cinnamate (EC), as environmentally friendly plasticizers for polylactide (PLA). Plasticized

Decarboxylation of cinnamic acids using a ruthenium sawhorse
International Journal of Sustainable Engineering, 2018 The ruthenium sawhorse has proven effective in the conversion of trans-cinnamic acid, and substituted trans-cinnamic acids, giving an effective source of biobased styrene and styrene analogues. The reaction is especially versatile, as it achieves product
