Arylboronic acidOxidative couplingNickel-catalyzed decarboxylative coupling reactions between aryl alkynyl carboxylic acids and arylboronic acids were developed. When aryl alkynyl carboxylic acids were reacted with arylboronic acids in the presence of NiCl2(10 mol%), 2,2-bipyridine (20 mol%), Na2CO3(...
CONSTITUTION:An organic chloride (e.g. chlorobenzene) having at least one chlorine atom on a ring of an aromatic hydrocarbon or heterocyclic hydrocarbon which may have a substituent group is reacted with carbon monoxide in the presence of an inorganic base (preferably Na2CO3 or K2CO3) at 150-...
Esterification - Esters are formed by the reaction between an alcohol and either an organic or an inorganic acid. The esterification reaction is undertaken in a reaction column that contains a solid resin catalyst. Click here for reaction, mechanism, typ
2.1. Reactants Cyclohexanecarboxylic acid (CHA, 98%), FeCl2 (98%) and FeCl3 (97%) were supplied by Sigma-Aldrich and H2O2 (30% w/v) by Panreac. All aqueous solutions for reaction were prepared at pH0 3.0 ± 0.1 using HCl (37% w/v; Panreac) in ultrapure water. H3PO4 (85 wt...

formula (n is 0 or 1) is made to react with iodine in the presence of an oxidizing agent such as nitric acid, hydrogen peroxide, persulfate, etc., and the obtained iodinated compound is made to react with carbon monoxide in the presence of a basic compound (e.g. NaOH, Na2CO3, etc....
R<2> is H, lower alkyl, cycloalkyl, etc.; R<3> is carboxy- protecting group] is reacted with a compound of formula II (R<4> is the same as R<2>; R<5> is H or the same as R<2>) in the presence of boron triflate or tin triflate and a base (e.g., Na2CO3, NaOH, et...
The resultant vitamin A is subsequently reacted with an acylating agent, such as acetic anhydride, in the presence of a tertiary amine, such as pyridine, or an alkaline metal carbonate, such as Na2CO3, preferably in an organic solvent, preferably at -10 to +50 deg.C to provide a ...
PREPARATION:A carboxylic acid halide derivative expressed by formula II (X1 is halogen) is reacted with an amino compound expressed by formula III in the presence of a base (e.g. triethylamine or Na2CO3) in an inert solvent, such as halogenated hydrocarbons or ethers, at -10 deg.C to ...
