The Selective N-Alkylation of Monoethanolamine
Alkyl derivatives of MEA are used in the production of surfactants, dyes, in the manufacture of drugs as a buffer substance and for the stabilization of emulsions, in the manufacture of herbicides, cosmetics, antihistamines, are also of practical interest [1]. It is widely known also as useful “acid” gases (H2S, CO2, SO2, etc.) as absorbents in the process of cleaning process for gases in oil r...

متن کاملShape Selective Alkylation of Biphenyl with 1-octene on ((Al+C3H7Cl)+C2H4) Catalysts
Alkylation of biphenyl with 1-octene was investigated using ((Al+C3H7Cl)+C2H4) catalysts. The catalytic activity of ((Al+C3H7Cl)+C2H4) for the alkylation was studied at different temperatures, mol ratios of biphenyl to 1-octene, reaction times and catalyst concentrations. It was shown that using this catalyst has more advantagous than another catalysts. Experiments show that by increasing t...
متن کاملMicrowave-assisted C-3 selective oxidative radical alkylation of flavones.
Flavones were directly alkylated at the C-3 position in moderate yields using a xanthate-based oxidative radical addition procedure. This methodology is a suitable synthetic tool for the direct substitution of the vinylic and unactivated C-H bond of the C ring of the flavone by an alkyl functionality under neutral conditions.
متن کاملCopper-catalysed α-selective allylic alkylation of heteroaryllithium reagents.
2-Allyl-substituted thiophenes and furans are synthesised efficiently in a direct procedure using 2-heteroaryllithium reagents and allyl bromides and chlorides catalysed by ligand-free copper(i). The reactions take place under mild conditions, with excellent α-selectivity, high functional group tolerance and good yields for the SN2 products.
