Kinetics and Mechanism of Reaction of Carbon Tetrachloride with Copper(0) in Dimethylformamide

“…The disappearance during reactions of the ESR signals of the stable 2,2,6,6-tetramethylpiperidine 1-oxide radical that is capable of reacting with radical intermediates provides further evidence for the radical nature of the process, since ESR signals of 2,2,6,6-tetramethylpiperidine 1-oxide do not appear after oxidation of Cu0 and reduction of mixtures with KI in acetate buffer and H 2 O 2 in alkaline medium [12,13].…”

“…The nonlinear v3[L] dependence shows that DMF molecules, too, are adsorbed on metal surface [schemes (10)3(12)] [6]. (12) In this case, the reaction rate has Eq. (13) [k`is given by Eq.…”

Reaction of Benzyl Bromide with Mn(0) in Dimethylformamide

“…The ESR spectra were taken directly from the reaction mixtures at 298 K by the procedure described in [10,11]. As a stable radical we used TEMPO [10,11] at the molar ratio Mn : PhCH 2 Br : DMF : TEMPO = 1 : 5 : 8 : 0.2.…”

“…As a stable radical we used TEMPO [10,11] at the molar ratio Mn : PhCH 2 Br : DMF : TEMPO = 1 : 5 : 8 : 0.2.…”

“…When a stable radical, 2,2,6,6-tetramethylpiperidyl-1-oxyl (TEMPO), reacting with radical intermediates, was added to the reaction mixture, its ESR signals disappeared in the course of the reaction, suggesting the radical mechanism of the oxidative dissolution of Mn(0) in the benzyl bromide3DMF systems, since the ESR signals of TEMPO do not appear after oxidation of Mn(0) to Mn(II) and reduction of the mixtures with KI in acetate buffer solution [10,11].…”
