Hypervalent iodine(III)-mediated decarboxylative acetoxylation at tertiary and benzylic carbon centers

open access: yesBeilstein Journal of Organic Chemistry, 2018
The decarboxylative acetoxylation of carboxylic acids using a combination of PhI(OAc)2 and I2 in a CH2Cl2/AcOH mixed solvent is reported. The reaction was successfully applied to two types of carboxylic acids containing an α-quaternary and a benzylic ...

Optimising the Decarboxylation of Anacardic Acid by Exploring the Temperature Effects

open access: yesJournal of Chemistry
Cashew nut shell liquid (CNSL) is one of the raw materials extracted from cashew nut shells (CNS). This liquid can be processed to produce cardanol through the decarboxylation of anacardic acid, a significant isolate from CNSL.

Crassulacean acid metabolism in the Gesneriaceae [PDF]

open access: yes, 1986
The occurrence of the Crassulacean acid metabolism (CAM) was studied in four epiphytic species of the Gesneriaceae: two neotropical species, Codonanthe crassifolia and Columnea linearis, and two paleotropical species, Aoschynanthus pulcher and ...

Synergistic Effects of Electricity and Light for Efficient Iron‐Catalyzed Recycling of Polystyrene Waste

open access: yesAngewandte Chemie International Edition, EarlyView.
The synergistic interplay of electricity, light and earth‐abundant, nontoxic iron catalysis allowed for the efficient recycling of post‐consumer polymers into value‐added products. This robust depolymerization strategy was viable on multigram‐scale, where the cathodic hydrogen evolution reaction presents an attractive opportunity for a green hydrogen ...

New cofactor supports α,β-unsaturated acid decarboxylation via 1,3-dipolar cycloaddition

open access: yesNature, 2015
The bacterial ubiD and ubiX or the homologous fungal fdc1 and pad1 genes have been implicated in the non-oxidative reversible decarboxylation of aromatic substrates, and play a pivotal role in bacterial ubiquinone (also known as coenzyme Q) biosynthesis ...

Hydrodeoxygenation of fatty acid methyl ester in gas oil blend–NiMoS/alumina catalyst

open access: yesGreen Processing and Synthesis, 2018
Hydrotreating of 10% fatty acid methyl ester (FAME) blended in gas oil was carried out by an NiMo-S/alumina catalyst and performed at an elevated temperature (300–400°C), a space velocity of 0.7–1.5 1/h and pressure 5 MPa.

Entry to 2-aminoprolines via electrochemical decarboxylative amidation of N‑acetylamino malonic acid monoesters

open access: yesBeilstein Journal of Organic Chemistry
The electrochemical synthesis of 2-aminoprolines based on anodic decarboxylation–intramolecular amidation of readily available N-acetylamino malonic acid monoesters is reported. The decarboxylative amidation under Hofer–Moest reaction conditions proceeds
