As for releasing in long-cherished desire, (A) the lube, or (B) the blend, when ending of condensation, the alkylation diphenylamine which remains is not separated from the akuridan product, under the conditions, hydrogen, the alkyl of C, and at the same time R, R, R, or R, at ...
In addition to allylic alcohols, an allylic ether (5l), amine (5 m), or ester (5n) could be used as an allylation reagent38.Fig. 4: The scope of allylation reagents.Reaction conditions: Ni(COD)2 (10 mol%), L6 (11 mol%), EtOH (0.5 mL), ketone ...
Application of this methodology to a quaternary salt from 2-dimethylaminomethyl-3-trimethylsilylmethyl-1,3-butadiene provides an expedient approach to 1,2-dimethylenecyclohexanes and their Diels–Adler derivatives. After displacement of the amine, a desilylative condensation catalyzed by tetrabutylammonium ...
PURPOSE:To reduce a nitron group into an amino group, by reducing a nitroalkyl phenyl ketone or a nitrobenzophenone in water or in an inert organic solvent in the presence of both Raney nickel and a cyanamide-aliphatic amine condensate, etc. under hydrogen pressure. CONSTITUTION:In water or ...
Disclosed herein is a composition comprising: A) a lubricant; and B) a mixture of antioxidants, wherein said mixture is prepared by the partial condensation of an alkylated diphenylamine with an aldehyde or ketone in the presence of an acidic catalyst
Oxidative condensation between arylacetaldehydes and primary amines gives the 2,5-disubstituted oxazoles 257 (Eq. 68).142 (68) The metal-free I(III) promoted reaction of chalcones 258 with ammonium acetate and iodobenzene diacetate gives 2,5-diaryloxazoles 259 (Eq. 69).143 (69) The three...

An Iridium/ketone dual catalysis pathway has been proposed (Fig.4c). The condensation of alkyl amine1with diazafluorenone4yields imine18, which is deprotonated at the α C−H bond to form 2-azaallyl anion1949. The delocalized carbanion19then undergoes asymmetric addition at the diazafluorenyl...
10. Use according to claims 1 to 9, characterized in that the acid groups for the ketone-aldehyde condensation or co-condensation products consist of carboxy groups, sulfo groups, sulfamido groups, sulfoxy groups, sulfoalkylamine groups or sulfoalkyloxy groups. 11. Use according to claims 1 ...
1) phenol-butanol ketone method; 2) phenol-methyl ketene method; 3) p-hydroxybenzaldehyde-acetone condensation-hydrogenation reduction method; 4) methoxybenzyl chloride -Ethyl acetoacetate method. However, these synthesis methods have problems such as the use of large amounts of acids, bases and high...
