Nickel(II)-Catalyzed Borylation of Alkenyl Methyl Ethers via C-O Bond Cleavage.
Organic Letters, 2020A new protocol has been developed for the borylation of conjugated alkenyl methyl ethers using B2Pin2 via C-O bond cleavage catalyzed by Ni(II). In this cross-coupling reaction, both E/Z isomers of alkenyl ethers are converted into (E)-alkenyl boronic ...

The reactions of methylene, produced by the photolysis of both ketene and diazomethane, with a number of simple ethers have been studied. Most of the data obtained refer to the gas phase but some liquid-phase results are also reported. Methylene in its singlet state has been found to insert in the various carbon hydrogen bonds in a near random fashion.

Synthesis of (+)-Spirolaxine Methyl Ether
The Journal of Organic Chemistry, 2006A short and efficient synthesis of (+)-spirolaxine methyl ether, a metabolite of the fungus Sporotrichum laxum with inhibitory activity against Helicobacter pylori, is described. The synthesis has been carried out by a Prins cyclization, to obtain the [6,5]-spiroketal system, and a Wadsworth-Emmons condensation, applied for the installation of the ...

Fluid Phase Equilibria, 2001
Abstract Thermodynamic properties of two fluorinated ethers, that meet the criteria of the potential new-generation refrigerants with considerably low global warming potential (GWP) and the zero ozone depletion potential (ODP), are studied in the present paper. The recommended candidates are pentafluoroethyl methyl ether, CF 3 CF 2 OCH 3 (245cbEβγ),
