FIELD: industrial organic synthesis.;SUBSTANCE: invention relates to improved method for manufacturing arylalkyl ethers used, for example, as intermediates for synthesis of drugs and flavor substances. Method comprises charging reactor with homogenous, at normal pressure, mixture containing hydroxyaromating...
=three alkyl groups). Examples of alkylating agents include nitrosamines, aliphatic epoxides, aflatoxins, lactones, nitrosoureas, nitrogen mustards, haloalkanes, aryl triazenes, and sultones (Dipple, 1995). The sites of substitution in DNA bases by alkylating agents are many (see Figure 26.2 in...
An alkyl and/or aryl silyl ether capped polyether surfactant useful in cleaning compositions. The polyether is described in conjunction with automatic dishwashing detergent composition having improved chlorine bleach stability comprising:(a) an active chlorine containing compound selected from the group consi...
Alkyl aryl ether productionPhenol compounds are O-alkylated with olefins in the presence of acid resin catalysts to give aryl alkyl ethers. In a preferred embodiment, the catalyst comprises perfluorosulfonic acid ion exchange resins.doi:US4299996 ARobert M. Parlman...

PURPOSE:To advantageously obtain an aralkyl aryl ether by reacting an alkoxyphenol with an aralkyl halide in a polar solvent. CONSTITUTION:An alkoxyphenol is reacted with an aralkyl halide using, preferably a basic compound or a phase-transfer catalyst, especially a phase-transfer catalyst such ...
Building molecular complexity from simple feedstocks through precise peripheral and skeletal modifications is central to modern organic synthesis. Nevertheless, a controllable strategy through which both the core skeleton and the periphery of an aromatic
Examples of suitable compounds of this type include: methyl tri15 phenylmethyl ether, benzyl methyl ether, benzhydrol, p-methylbenzyl alcohol, phenyl-p-tolylcarbinol, tri-p-tolylcarbinol, and the like. As the catalyst for effecting the production of my new p-nitroalkyl aralkyl ethers, I ...

Regarding unactivated alkyl chlorides, thermal Pd-catalyzed conditions reported by the Fu group were applicable but limited to intramolecular annulations with only four examples that proceed under the assistance of the Thorpe-Ingold effect15. The Zhou group reported a protocol for alkyl iodides amenable...
