Khan, Raihana Imran; Pitchumani, Kasi published the artcile< A pyridinium modified β-cyclodextrin: an ionic supramolecular ligand for palladium acetate in C-C coupling reactions in water>, Electric Literature of 112-63-0, the main research area is bromobenzene phenylboronic acid pyridinium cyclodextrin catalyst Suzuki coupling; biaryl preparation green chem; styrene aryl halide pyridinium cyclodextrin catalyst Heck coupling; aryl alkene preparation green chem.
An ionic Pd(II) complex stabilized by a water soluble pyridinium modified β-cyclodextrin was prepared and characterized by NMR, mass spectrometry, FT-IR spectroscopy, UV-visible spectroscopy and DLS (dynamic light scattering). The resulting Pd(II)@Pyr:β-CD complex showed very good catalytic activity in Suzuki-Miyaura and Heck C-C coupling reactions in an environmentally benign water medium. Good to excellent yields were obtained for the coupling of various aryl halides including chlorides with phenylboronic acid/styrene using a catalytic amount of Pd(II)@Pyr:β-CD. This homogeneous catalyst can be reused and recycled more than six times with only marginal loss of its catalytic activity.
Green Chemistry published new progress about Binding energy. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Electric Literature of 112-63-0.
