CATALYST AND PRECURSOR THEREOF AND METHOD OF FORMING DIALKYL CARBONATE

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

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.

FREE-RADICAL TRANSFORMATIONS OF ALKYL ORTHOFORMATES IN THE LIQUID PHASE

The homolytic liquid-phase reactions of trialkoxymethanes, initiated by tert-butoxyl radicals, in the range 120-150 deg C were investigated.A mechanism of an unbranched chain process was established for the fragmentation of the trialkoxymethanes with quadratic determination at the alkyl radicals; as a result the corresponding dialkyl carbonates, alkyl formates, alkanes, and carbonyl compounds are obtained.The relative rate constants (k3/k4) of the chain propagation and termination reactions and the kinetic parameteres of the transformations of the ortho esterswere calculated.The differences in the activation energies for cleavage of the C-H bonds adjacent to one and three oxygen atoms was determined (ΔE = 5.0-6.0 kcal/mole).The trialkoxymethanes are close in reactivity to 1,3-dioxanes, are inferior to 1,3-dioxolanes, and superior to dialkoxymethanes.
