A Radical Approach to Syntheses and Mechanisms
… performed by previous researchers indicate N,N-dimethylaniline radical cations deprotonate in the presence of the bases acetate and pyridine. By studying the electrochemical kinetics of the reaction of para substituted N,N-dimethylaniline radical cations with acetate anion, we have produced …

A Kinetic and Thermodynamic Study of Exciplex Fluorescence Quenching by Ion Pairs
… to quench the fluorescence of the pyrene-N,N-dimethylaniline exciplex in solvents of low dielectric constant. Linear Stern-Volmer plots are obtained for quenching of both lifetime and intensity in dioxane. However, mechanistic complications are implied by intercepts exceeding unity and by the …

Touch-and-go chemistry: development of materials for and demonstration of a contact-initiated polymerization
… Particles were then functionalized with N,N-dimethylaniline (DMA) and benzoyl peroxide (BPO) groups which co-initiate free radical polymerizations. The mechanism by which they co-initiate requires contact between the DMA and BPO molecules. When DMA and BPO were conjugated to complementary …

Synthesis and application of Fischer carbene complexes of group 6, 8 and 9 transition metals
… substituents (thiophene, 2,3´-bithiophene, N,N-dimethylaniline and ferrocene) to modify the reactivity of these complexes. Synthetic challenges included metal acylate O-alkylation to yield the desired FCCs, in contrast to the commonly found metal alkylation that leads to related ketone formation …

The study of [beta]-cyclodextrin interactions with sugars using "inhibition kinetics" and the bromination of pyrimidine derivatives
… (2-DAPy), aniline and N,N -dimethylaniline were also studied.

Design, Synthesis and Study of Novel Nucleobase Analogs
… coupling reaction between 5-diazouracil and N,N-dimethylaniline. Fluorescence quenching experiments were performed between the nucleobase quencher and the fluorophores phenylpyrrolocytidine (pC), and pyrene to determine viable FRET pairs for use in molecular beacon constructs.

Advances in alkali-metal-mediated manganation and comparisons with magnesiation
… Highlights include the meta manganation of N, N-dimethylaniline [(TMEDA)Na(TMP)(m-C₆H₄-NMe₂)Mn(TMP)] (21), the para manganation of N, N-diisopropylaniline [(TMEDA)Na(TMP)(p-C₆H₄NiPr₂)Mn(TMP)] (22) and the novel 6-position mangantion of N, N-dimethyl-1-naphthylamine …

New Polyazine-Bridged Ru(II),Rh(III) and Ru(II),Rh(I) Supramolecular Photocatalysts for Water Reduction to Hydrogen Applicable for Solar Energy Conversion and Mechanistic Investigation of the Photocatalytic Cycle
… the RuII,RhI species in the presence of DMA (N,N-dimethylaniline). The observed H2 production from water using [(bpy)2Ru(dpp)RhCl(tpm)](PF6)4 and [(bpy)2Ru(dpp)RhCl(tpy)](PF6)4 established that two halides on RhIII are not necessary in the dpp-bridge RuII,RhIII supramolecular …

Design and Modification of Polyazine-Bridged Ru(II),Rh(III) Bimetallic and Trimetallic Supramolecular Complexes Applicable in Solar Energy Harvesting for the Photocatalytic Reduction of Water to Hydrogen
… presence of the sacrificial electron donor N,N-dimethylaniline (DMA) results in multi-electron collection at Rh, thereby converting Rh(III) to Rh(II) to Rh(I) accompanied by halide loss at each step. This establishes the Ru(II),Rh(III),Ru(II) and Ru(II),Rh(III) complexes as photochemical …

Polyazine-Bridged Ru(II),Pt(II) Trimetallic and Tetrametallic Supramolecular Complexes Exhibiting Unusual Excited State Dynamics Important in Catalysis and PDT Drug Development
… and the sacrificial electron donor, DMA (N,N-dimethylaniline), the tetrametallic complexes collect electrons on the ligand À* orbitals of the central Ru to serve as photoinitiated electron collectors. The photocatalytic activity in H2 production is drastically impacted by BL" identity, …
