Convenient iron-catalyzed reductive aminations without hydrogen for selective synthesis of N-methylamines

open access: yesNature Communications, 2017
N-methylated amines display high biological activity in living organisms. Here, the authors show the convenient synthesis of a wide range of biologically relevant N-methylamines via reduction of nitrobenzenes using a recyclable iron catalyst and ...

Widespread atypical response regulator SecR governs bacterial growth on methylamines through the serine cycle [PDF]

open access: yesCommunications Biology
Microbial utilization of methylamines (MAs) exerts profound effects on biogeochemical carbon cycles, yet the regulatory mechanisms enabling bacterial adaptation to fluctuating MAs availability remain elusive.

Halophilic Methylotrophic Methanogens May Contribute to the High Ammonium Concentrations Found in Shale Oil and Shale Gas Reservoirs

open access: yesFrontiers in Energy Research, 2019
Flow-back and produced waters from shale gas and shale oil fields contain high ammonium, which can be formed by methanogenic degradation of methylamines into methane and ammonium. Methylamines are added to fracturing fluid to prevent clay swelling or can

Zwitterionic cellular polymer enabled reductive fixation of CO2 for N-methylation of amines

open access: yesGreen Synthesis and Catalysis, 2023
Using heterogeneous catalysts to promote the construction of the C–N bond between amines and CO2 under mild conditions is a challenge yet. Herein, we synthesized a novel zwitterionic polymer (PDDC) with a cellular structure via self-complexation of ...

The local structure in liquid methylamine and methylamine–water mixtures [PDF]

open access: yesThe Journal of Chemical Physics, 2000
Molecular dynamics (MD) computer simulations are carried out on liquid methylamine and on 10 and 30 wt % aqueous solutions of methylamine. The local three-dimensional structure in these liquid systems is investigated using standard one-dimensional radial distribution functions and the fully three-dimensional measure of the local structure around the ...
