Unexpectedly efficient activation of push–pull nitriles by a PtII center toward dipolar cycloaddition of Z-nitrones

Abstract: Pt(II)-coordinated NCNR'(2) species are so highly activated towards 1,3-dipolar cycloaddition (DCA) that they react smoothly with the acyclic nitrones ArCH=N(+)(O(-))R'' (Ar/R'' = C(6)H(4)Me-p/Me; C(6)H(4)OMe-p/CH(2)Ph) in the Z-form. Competitive reactivity study of DCA between trans-[PtCl(2)(NCR)(2)] (R = Ph and NR'(2)) species and the acyclic nitrone 4-MeC(6)H(4)CH=N(+)(O(-))Me demonstrates comparable reactivity of the coordinated NCPh and NCNR'(2), while alkylnitrile ligands do not react with the dipole.

“…In the past decade, a great attention has been paid to electrophilic activation of the C≡N bond in nitriles (Bokach, 2010;Bokach et al, 2011a;Bokach et al, 2011b;Kritchenkov et al, 2011;Kritchenkov et al, 2012;Kukushkin & Pombeiro, 2002;Makarycheva-Mikhailova et al, 2007). In a addition an interest in compounds which contain borane clusters is caused by their potential application in medicine, homogeneous catalysis, for non-linear optics and luminescent materials creation, as potential metal extractants, agents for anion recognition and building blocks for coordination polymers creation, etc (Dash et al, 2011).…”
