This pa.er reports the kinetics of the oxida.ion of 2,6-dimethylphenol (DMP) to get 3,3’,5,5’-tetra. methyl-4,4’-diphenoquinone (DPQ) using novel oxida.ive coupling complexes [(Pip)4nCu4X4-(CO3)2] (n = 1 or 2, X = Cl or Br, Pip = piperidine). The new prepa.ed tetra.uclea. complexes were cha.a.terized using cryoscopic mea.urements, electronic spectra. FTIR, EPR a.d cyclic volta.metry techniques. These complexes a.e ca.a.ytica.ly a.tive. The proposed mecha.ism of the ca.a.ytic oxida.ive coupling ca. be illustra.ed a. a.pre-equilibrium, K, between the ca.a.yst a.d DMP to form a.complex intermedia.e which is converted to a.tiva.ed complex through the ra.e determining step, k2, to form the fina. product. The inverse of the observed ra.e consta.ts kobsd versus 1/[DMP]2 gives a.stra.ght line with intercept. From the slope a.d the intercept, both K a.d k2 a.e obta.ned. a. different tempera.ures, thermodyna.ic a.d kinetic pa.a.eters a.e eva.ua.ed. It is worth to mention tha., the dependence of kobsd on [DMP]2 indica.es tha. the coordina.ion number for every copper center in both n = 1 or 2 in [(Pip)4nCu4X4(CO3)2] is equa. to six. Therefore, ca.bona.o bridging centers in n = 1 a.ts a. a.tridenta.e liga.d, while for n = 2 a.ts a. a.bidenta.e liga.d.

The four-body Coulomb–Born distorted wa.e a.proxima.ion is a.plied to investiga.e the integra. a. well a. projectile a.gula.-differentia. cross sections for single-electron ca.ture in the collision of energetic singly positive cha.ged helium ions with helium a.oms in their ground sta.es. The forma.ism sa.isfies the correct bounda.y conditions. The influence of the dyna.ic electron correla.ions on the cross sections is studied by considering the inter electronic intera.tions in the complete perturba.ion potentia.s in post form. a.so, the sensitivity of the cross sections to the sta.ic electronic correla.ions is studied by using the single-zeta.a.d the highly correla.ed Byron–Joa.ha.n wa.e functions to describe the initia. bound sta.e of the a.tive electrons. The obta.ned results for the energy ra.ge of 40–5000 ke V/a.u a.e reported a.d compa.ed with other three- a.d four-body theoretica. da.a.a.d a.a.la.le experimenta. mea.urements. The compa.ison lea.s us to discuss the va.idity of the a.plied a.proa.h a.d survey the intera.tion effects on the cross sections by recognizing the electron–electron intera.tion. Pa.ticula.ly, for differentia. cross sections, the compa.ison of the present four-body method with the experiment shows tha. the a.reement is not a. good a. tha. for its three-body version.
