Kinetic analysis was used as a tool for rational optimization of a catalytic, direct substitution of alcohols to enable the selective formation of unsymmetrical ethers, thioethers, and Friedel-Crafts alkylation products using a moisture-tolerant and commercially available zirconium complex (2 to 8 mol%). Operating in air and in the absence of dehydration techniques, the protocol furnished a variety of products in high yields, including glycosylated alcohols and sterically hindered ethers. In addition, the kinetic studies provided mechanistic insight into the network of parallel transformations that take place in the reaction, and helped to elucidate the nature of the operating catalyst.

Paragraph 0042-0045, (2017/02/28)
The invention provides a synthetic method of asymmetrical ether in the field of organic synthesis. The general equation of reaction is defined in the specification. In the equation, R-OH is benzyl alcohol, p-methoxy benzyl alcohol, tert-butyl alcohol, diphenyl carbinol or triphenylmethanol; and R'OH is common alkyl alcohol or a compound containing hydroxyl groups. A gold catalyst required by the reaction is Ph3PAuCl, Ph3PAuNTf2, HAuCl4, NaAuCl4, Ph3PAuOTf, Ph3PAuSbF6, IPrAuCl or nano-gold. A medium required by the reaction is solvent-free, and is toluene, mesitylene, 1,2-dichloroethane, tetrahydrofuran, acetonitrile or acetone. The reaction is implemented by heating through a microwave reactor. The method has advantages as follows: raw materials are easily available; operation is simple; the range of application is wide; atom economy is good; and the reaction is green.

Paragraph 0012, (2016/11/14)
PROBLEM TO BE SOLVED: To provide a method of producing a vinylbenzyl(fluoroalkyl) ether industrially at low costs. SOLUTION: A method of producing a vinylbenzyl(fluoroalkyl) ether of formula (1) (in the formula, Rf is a fluoroalkyl group, and n is an integer of 1-3) comprises reacting a fluoroalkyl alcohol of formula (2) (in the formula, Rf is a fluoroalkyl group, and n is an integer of 1-3) with chloromethylstyrene in a solvent selected from tertiary alcohols, nitrogen-containing organic solvents and sulfur-containing organic solvents in the presence of a solid alkali.
