Electrochemical Synthesis of Peptides Mediated by Triphenylphosphine

Triphenylphosphine mediated synthesis of functionalized aryl-vinyl ethers from7-hydroxy coumarin and methyl acetylene carboxylate

7-hydroxy coumarin undergoes neutral conditions with alkyl propiolates in the presence of triphenylphosphine, and bysubstituation the corresponding aryl vinyl ethers was obtained in good yields

TRIPHENYLPHOSPHINE CATALYZED AROMATIC ELECTROPHILIC SUBSTITUTION OF 2-HYDROXYACETOPHENONE MEDIATED BY VINYLTRIPHENYLPHOSPHONIUM CATION

Protonation of the highly reactive 1:l intermediate produced in the reaction between triphenylphosphine and dimethyl acetylenedicarboxylate by 2- hydroxyacetophenone leads to vinyltriphenylphosphonium salt, which undergoes aromatic electrophilic substitution reaction with the conjugate base to produce compounds 4,5, and 6 in 1 : 1.2:0.5 ratios

Synthesis of magnetic graphene-Fe3O4 nanocomposites by electrochemical exfoliation method

Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), ...

triphenylphosphine catalyzed aromatic electrophilic substitution of 2-hydroxyacetophenone mediated by vinyltriphenylphosphonium cation

protonation of the highly reactive 1:l intermediate produced in the reaction between triphenylphosphine and dimethyl acetylenedicarboxylate by 2- hydroxyacetophenone leads to vinyltriphenylphosphonium salt, which undergoes aromatic electrophilic substitution reaction with the conjugate base to produce compounds 4,5, and 6 in 1 : 1.2:0.5 ratios
