Usage

General Description

Butane, 2-methoxy-2,3-dimethyl- is a chemical compound commonly referred to as MTBE. It is a flammable liquid with a gasoline-like odor that is used as a fuel additive to boost the oxygen content in gasoline and improve its combustion efficiency. MTBE is also used as a solvent in various industrial processes and as a reagent in organic synthesis. However, its use has been increasingly restricted due to concerns about its potential to contaminate groundwater and its negative health effects, including its carcinogenic properties. As a result, many countries have phased out or banned the use of MTBE in gasoline.

Hydride Ion Transfer Reactions in the Gas Phase. Pressure Dependence of Reaction Efficiency as a Criterion for the Recognition of Anchimeric Assistance

The efficiency (kobs/kcoll) of the gas phase hydride ion transfer from 2,2-dimethylbutane to tert-butyl cation displays a pronounced positive pressure dependence, which suggests significant anchimeric assistance of the methyl groups of 2,2-dimethylbutane adjacent to the departing CH2 hydride in the transition state.

Development of efficient palladium catalysts for alkoxycarbonylation of alkenes

Herein, we report a general and efficient Pd-catalysed alkoxycarbonylation of sterically hindered and demanding olefins including a variety of tri-, tetra-substituted and 1,1-disubstituted alkenes. In the presence of 1,3-bis(tert-butyl(pyridin-2-yl)phosphanyl)propane L3 or 1,4-bis(tert-butyl(pyridin-2-yl)phosphanyl)butane L4 the desired esters are obtained in good yields and selectivities. Similar transformation is obtained using tertiary ether as showcased in the carbonylation of MTBE to the corresponding linear ester in high yield and selectivity.

Benzene-based diphosphine ligands for alkoxycarbonylation

The invention relates to benzene-based diphosphine ligands for alkoxycarbonylation. Specifically, the invention relates to compounds of formula (I), where m and n are each independently 0 or 1; R1, R2, R3, R4 are each independently selected from -(C1-C12)-alkyl, -(C3-C12)-cycloalkyl, -(C3-C12)-heterocycloalkyl, -(C6-C20)-aryl, -(C3-C20)-heteroaryl; at least one of the R1, R2, R3, R4 radicals is a -(C3-C20)-heteroaryl radical; and to the use thereof as ligands in alkoxycarbonylation.
