Compatibility of selected, commercially available ruthenium olefin metathesis catalysts with ethyl lactate as solvent was evaluated using a range of substrates and conditions. In addition, the preparation of a metathesis catalyst in simplified manner by using the advantages of ethyl lactate was accomplished. The application of ethyl lactate facilitates product isolation (also allowing for lower Ru-contamination in crude metathesis products) and improves the overall green angle of olefin metathesis.

The ability to use unprotected carbohydrates in olefin metathesis reactions in aqueous media is demonstrated. Using water-soluble amine-functionalized Hoveyda-Grubbs catalysts under mildly acidic aque...
Iron(III)-catalyzed carbonyl-olefin ring-closing metathesis employs reactivity not typically observed in Lewis acid-catalyzed reactions. In converting a ketone with a pendant olefin into a cycloalkene...
Grafting a Mo oxo alkylidene on silica (partially dehydroxylated at 700 °C) affords the first example of a well-defined silica-supported molybdenum oxo alkylidene, an analogue of the putative active ...
Isomerizing olefin metathesis is currently undergoing a transformation from laboratory curiosity to powerful synthetic concept at the heart of orthogonal tandem catalysis. In this process, an isomeriz...
The precise synthesis of polymers derived from alkyl lactate ester acrylates is reported for the first time. Kinetic experiments were conducted to demonstrate that Cu(0) wire-catalyzed single electron...
No clinical evidence has been yet published regarding the comparison of postoperative pain after removal of the root canal fillings with or without solvent. The aim of this study was to ev...
Clinical triple-blind randomized controlled trial to assess the use of two different mouthwashes to reduce the oral colonization by gramnegative bacteria in patients with chemotherapy indu...
The investigators hypothesize that oral omega-3-acid ethyl esters (Lovaza, GlaxoSmithKline, Research Triangle Park, NC) will decrease dry-eye related symptoms as well as clinical markers a...
The study will consist of five occasions with one week in between. BOLD signal intensity of the hypothalamus will be measured using fMRI. Measurements will be done before and after drinkin...
The purpose of this study is to determine whether laboratory storage of samples affects the amount of lactate over 3 years. Lactate is a natural substance normally present in the body. La...
A cytochrome form of lactate dehydrogenase found in the MITOCHONDRIA. It catalyzes the oxidation of L-lactate to PYRUVATE with transfer of electrons to CYTOCHROME C. The enzyme utilizes FMN and PROTOHEME IX as cofactors.
A mobile, very volatile, highly flammable liquid used as an inhalation anesthetic and as a solvent for waxes, fats, oils, perfumes, alkaloids, and gums. It is mildly irritating to skin and mucous membranes.
A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist.
A gas that condenses under slight pressure. Because of its low boiling point ethyl chloride sprayed on skin produces an intense cold by evaporation. Cold blocks nerve conduction. Ethyl chloride has been used in surgery but is primarily used to relieve local pain in sports medicine.
Organic compounds having ethyl groups bound to an oxygen atom
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism ...
