The photoenzymatic decarboxylation of fatty acids to alkanes is proposed as an alternative approach for the synthesis of biodiesel. By using a recently discovered photodecarboxylase from Chlorella variabilis NC64A (CvFAP) we demonstrate the irreversible preparation of alkanes from fatty acids and triglycerides. Several fatty acids and their triglycerides are converted by CvFAP in near‐quantitative

alkyl amino carbene (Ru–CAAC) olefin metathesiscatalysts perform extraordinarily in metathesis macrocyclization and ethenolysis, but previous studies have been limited to the use of five-membered CAAC (CAAC-5) ligands. In this work, we synthesized a different group of rutheniumcatalysts with more σ-donating and π-accepting six-membered CAAC (CAAC-6) ligands, and their metathesisactivity was probed

When used as solvent, chloroform was found to act as a hydrogen atom donor in Barton reductive decarboxylation reactions. Chloroformoffers a substantial practical advantage over pre-existing hydrogen atom donors.

can be exploited for the production of biofuels from fatty acids and triglycerides. With Coulomb efficiencies (CE) of up to 50 %, the electrochemical decarboxylation of fatty acids in methanolic and ethanolicsolutions leads to the formation of diesel‐like olefin/ether mixtures. Triglycerides can be directly converted in aqueous solutions by using sonoelectrochemistry, with olefins as the main products
disease caused by the intake of trans fattyacids, a method to eliminate trans fattyacids from foods has become a critical issue. Herein, we engineered fattyacid photo-decarboxylase from Chlorella variabilis (CvFAP) to selectively catalyze the decarboxylation of trans fattyacids to yield readily-removed hydrocarbons and carbon dioxide, while cis fattyacids remained unchanged.
