A method for synthesizing halogenated organic compounds, such as halogenated alkenyl group-containing and halogenated alkyl group-containing compounds having a heteroatom (e.g., O,N.S) coupled to a carbon atom of a halogenated alkenyl or halogenated alkyl group, involves reacting a halogenated olefin such as a chloro-substituted trifluoropropenyl compound with an active hydrogen-containing organic compound such as an alcohol (e.g., an aliphatic monoalcohol, aliphatic polyalcohol, or a phenolic compound), a primary amine, a secondary amine or a thiol.

A carbonylation system comprising at least one carbon monoxide producing chamber and at least one carbon monoxide consuming chamber forming an interconnected multi-chamber system, said interconnection allowing carbon monoxide to pass from the at least one carbon monoxide producing chamber to the at least one carbon monoxide consuming chamber, said at least one carbon monoxide producing chamber containing a reaction mixture comprising a carbon monoxide precursor and a catalyst, said at least one carbon monoxide consuming chamber being suitable for carbonylation reactions, said interconnected multi- chamber system being sealable from the surrounding atmosphere during carbonylation.
Describes a method for obtaining substantially pure chloromethyl chloroformate from a chloroformate mixture comprising chloromethyl chloroformate and methyl chloroformate by heating the chloroformate mixture in a reaction zone at temperatures ranging from at least 50° C. to the reflux temperature of the chloroformate mixture in the reaction zone while simultaneously removing volatile gaseous decomposition products from the reaction zone. Dichloromethyl chloroformate may also be present in the chloroformate mixture.

Nitroarenes are reductively cyclized with an array of tetraalkylammonium halides and trialkylarnmonium chlorides in the presence of a catalytic amount of a ruthenium catalyst along with tin(II) chloride dihydrate at 180° to afford the corresponding quinolines in moderate to good yields. The addition of tin(II) chloride dihydrate is necessary for the effective formation of quinolines and toluene is

Synthesis of alkyl arylethers via copper‐catalyzed etherizations of electron‐deficient aryl fluorides with quaternary ammonium bromides and water has been developed. In the presence of Cu(OAc)2, POPh3 (L4) and Cs2CO3, a variety of electron‐deficient aryl fluorides underwent the reaction with quaternary ammonium bromides and H2O in moderate to good yields. The mechanism was also discussed.
已经开发了通过缺电子的芳基氟化物与溴化季铵和水的铜催化醚化反应来合成烷基芳基醚的方法。在存在Cu(OAc)2,POPh 3(L4)和Cs 2 CO 3的情况下,各种缺电子的芳基氟化物与季铵溴化物和H 2 O反应的产率中等至良好。还讨论了该机制。
