Harnessing visible-light energy for unbiased organic photoelectrocatalysis: Synthesis of: N -bearing fused rings

In this research, we realized the conversion of visible light to electrical energy and C-H activation by the synergistic catalytic effect of visible-light and photoelectric current. An atom-economical and environment-friendly self-biasing interfacial photo-electrocatalytic method for cascade C-H activation/cyclization is provided to construct N-containing fused ring compounds using an m-BiVO4 film as a photoanode. There are obvious advantages of this transformation due to no external bias and a small overpotential, saving electrical energy and avoiding excessive oxidation of malononitrile to achieve better chemical reactivity and selectivity. Meanwhile, the recovered photoanode could be used more than ten times. This journal is

Method for preparing alpha-aminonitrile and product and application thereof

The invention discloses a method for preparing alpha-aminonitrile, which comprises the following steps: by using tertiary amine and benzoyl cyanide as reactants, carrying out visible light irradiationin an organic solvent under the condition of oxygen or

Electrochemically promoted oxidative α-cyanation of tertiary and secondary amines using cheap AIBN

The electrochemical α-cyanation of tertiary and secondary amines has been developed by using a cheap cyanide reagent, azobisisobutyronitrile (AIBN). The CN radical, generated throughn-Bu4NBr-meidated electrochemical oxidation, participates in a novel α-cyanation reaction under exogenous oxidant-free conditions.

Visible light promoted photoredox C(sp3)-H bond functionalization of tetrahydroisoquinolines in flow

A merger of organocatalysis and visible light photoredox catalysis performed in flow allowed access to a wide range of functionalizedN-aryl-substituted tetrahydroisoquinolines (THIQs) in a formal C-H oxidation/Mannich reaction. Strecker type functionaliza

Electrochemical strategies for: N -cyanation of secondary amines and α C -cyanation of tertiary amines under transition metal-free conditions

Transition metal-free electrochemical approaches for the N-cyanation of secondary amines and the α C-cyanation of tertiary amines have been well established, with products being obtained in moderate to good yields and with good functional group tolerance under ambient conditions. The synthetic application of the protocols has been highlighted through scale-up experiments in a galvanostatic mode. Preliminary mechanistic investigation has confirmed that TBAB played a critical role in N-cyanation transformation and has indicated that the transformation might proceed via a free radical process.

Electron Donor-Acceptor Complex-Initiated Photochemical Cyanation for the Preparation of α-Amino Nitriles

An electron donor-acceptor complex-initiated α-cyanation of tertiary amines has been described. The reaction protocol provides a novel method to synthesize various α-amino nitriles under mild conditions. The reaction can proceed smoothly without the presence of photocatalysts and transition metal catalysts, and either oxidants are unnecessary or O2 is the only oxidant. The practicality of this method is showcased not only by the late-stage functionalization of natural alkaloid derivatives and pharmaceutical intermediate, but also by the applicability of a stop-flow microtubing reactor.

Oxidative cyanation of: N-aryltetrahydroisoquinoline induced by visible light for the synthesis of α-aminonitrile using potassium thiocyanate as a "cN" agent

PIFA-Promoted, Solvent-Controlled Selective Functionalization of C(sp2)-H or C(sp3)-H: Nitration via C-N Bond Cleavage of CH3NO2, Cyanation, or Oxygenation in Water

A novel nitration (via C(sp3)-N breaking/C(sp2)-N formation with CH3NO2) mediated by [bis(trifluoroacetoxy)iodo]benzene (PIFA) is described. The NO2 transfer from CH3NO2 to the aromatic group of the substrate is possible with careful selection of the solvent, NaX, and oxidant. In addition, the solvent-controlled C(sp2)-H functionalization can shift to an α-C(sp3)-H functionalization (cyanation or oxygenation) of the α-C(sp3)-H of cyclic amines.
