Solvent-Free Synthesis of Glycidyl Ethers Investigating Factors Influencing the Yield of Alkyl Glycidyl Ethers
Surfactants are a widely used group of chemicals. With a range of applications from soaps to paints and from hygiene products to asphalt they are one of the most diverse product groups available. AkzoNobel in Stenungsund uses glycidyl ethers as intermediates in the productions of some of their surfactants. These glycidyl ethers are produced with some hazardous compounds, which make the handling...
متن کاملMutagenicity of aromatic glycidyl ethers with Salmonella.
6 aromatic glycidyl ethers containing naphthyl, biphenyl or benzylphenyl substituents were synthesized. These epoxides together with the commercially available compounds 2-biphenylyl glycidyl ether were examined for dose-mutagenicity relationships using the plate incorporation Ames test with Salmonella typhimurium strains TA100 and TA1535. Structure-mutagenicity relationships were further exami...
متن کاملOxidative cleavage of allyl ethers by an oxoammonium salt.
A method to oxidatively cleave allyl ethers to their corresponding aldehydes mediated by an oxoammonium salt is described. Using a biphasic solvent system and mild heating, cleavage proceeds readily, furnishing a variety of α,β-unsaturated aldehydes and ketones.
متن کاملEnantioselective detoxication of optical isomers of glycidyl ethers.
The detoxication of the enantiomers of glycidyl 4-nitrophenyl ether (GNPE), (-)-(R)- and (+)-(S)-GNPE, and glycidyl 1-naphthyl ether (GNE), (-)-(R)- and (+)-(S)-GNE, by rat liver glutathione transferase and epoxide hydrolase was studied. Enantioselectivity was observed with both enzymes favoring the (R)-isomers as determined by the formation of conjugate, diol, and remaining substrate measured ...
متن کاملSynthesis of alkynyl ethers and low-temperature sigmatropic rearrangement of allyl and benzyl alkynyl ethers.
Alpha-alkoxy ketones 3 can be transformed into 1-alkynyl ethers 5 by a two-step procedure involving formation of the enol triflate or phosphate and base-induced elimination. Performing the same reaction sequence with allylic alcohols (R2OH, R2 = allyl) furnishes instead gamma,delta-unsaturated carboxylic acid derivatives 6, derived from [3,3]-sigmatropic rearrangement of the intermediate allyl ...
