Stoichiometric and electrocatalytic production of hydrogen peroxide driven by a water-soluble copper(ii) complex

Abstract

Herein, a water-soluble molecular copper complex was investigated as a catalyst for O2 reduction in both water and an organic solvent.

Influence of the spatial distribution of copper sites on the selectivity of the oxygen reduction reaction

“…Mononuclear Cu complexes have been explored to catalyze the ORR. [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] Additionally, several dinuclear complexes have been investigated to induce a cooperative effect during ORR catalysis. [35][36][37][38] We have recently shown that the mononuclear complex [Cu(tmpa)(solv)] + (Cu-tmpa, tmpa = tris(2-picolyl) amine) shows exceptionally high ORR catalytic performance with a turn-over frequency (TOF) of almost 2 million per second.…”

A mononuclear nonheme manganese(III)‐acylperoxo complex: Synthesis, characterization, and reactivity studies

“…The manganese(II) complex bearing N , N ‐bis(2‐picolyl)amine backbone with a pendant ethanol side chain (HN 3 O; 2‐(bis[pyridin‐2‐ylmethyl]amino)ethanol), [Mn(HN 3 O)(CH 3 CN)(ClO 4 )](ClO 4 ) ( 1 ), and [Mn(HN 3 O)]Cl 2 were synthesized according to the modified literature methods 38,39 …”

An end-on bis(μ-hydroxido) dimanganese(ii,iii) azide complex for C–H bond and O–H bond activation reactions

“…A white Mn( ii ) complex was prepared by following a modified literature procedure (details can be found in the ESI†). 9 The electrospray ionization mass spectrometry (ESI MS) spectrum exhibited a prominent peak at m / z of 441.1, whose mass and isotopic distribution patterns corresponded to a monomeric Mn complex, [Mn(HN 3 O 2 )(ClO 4 )] + (calculated m / z of 441.1) (Fig. S1a, ESI†).…”
