CATALYST AND PRECURSOR THEREOF AND METHOD OF FORMING DIALKYL CARBONATE
-
Paragraph 0036, (2021/06/22)
A method of forming dialkyl carbonate is provided, which includes introducing carbon dioxide into a catalyst to form dialkyl carbonate, wherein the catalyst is formed by activating a catalyst precursor using alcohol, wherein alcohol is R3—OH, and R3 is C1-12 alkyl group or C5-12 aryl or heteroaryl group. The catalyst precursor is formed by reacting Sn(R1)2(L)2 and Ti(OR2)4, and Sn(R1)2(L)2 and Ti(OR2)4 have a molar ratio of 1:2 to 2:1. R1 is C1-10 alkyl group, R2 is H or C1-12 alkyl group, and L is O—(C═O)—R5, and R5 is C1-12 alkyl group. The dialkyl carbonate is

A useful conversion of alcohols to alkyl fluorides via their fluoroformates is introduced. The fluoroformates are obtained in nearly quantitative yield from the alcohols by treatment with COF2 (generated in situ from bis(trichloromethyl) carbonate) in ether with KF as an added acid scavenger. The neat fluoroformates are cleaved to the fluorides by heating at 120-125°C using hexabutylguanidinium fluoride (HBGF) as the catalyst.

The reaction kinetics and the reactivity of ethyl orthoformate were studied in joint transformations with 1,3-dioxane, 1,1-dialkoxyalkanes, and hexyl orthoformate, initiated by tert-butyl peroxide.It was established that the corresponding dialkyl carbonates and esters are formed as a result of specific radical-chain transformations.From the ratio of the products in the range 120-150 deg C it was determined that alkyl orthoformates are more reactive than linear and cyclic acetals.
