A Facile Route for Stabilizing Highly Reactive ArTeCl Species Through the Formation of T-Shaped Tellurenyl Chloride Adducts: quasi-Planar Zwitterionic [HPy]TeCl2 and [HPm]TeCl2; Py = 2-pyridyl, Pm = 2-(4,6-dimethyl)pyrimidyl

Two new stable T‐shaped tellurenyl chloride adducts, viz., [HPy*]TeCl2 (1) and [HPm*]TeCl2 (2) [Py* = 2‐pyridyl, Pm* = 2‐(4,6‐dimethyl)pyrimidyl], act as close chemical analogs of highly unstable monomeric Py*TeCl and Pm*TeCl. The quasi‐planar zwitterionic structures of 1 and 2 have been studied by...

Description
Summary:Two new stable T‐shaped tellurenyl chloride adducts, viz., [HPy*]TeCl2 (1) and [HPm*]TeCl2 (2) [Py* = 2‐pyridyl, Pm* = 2‐(4,6‐dimethyl)pyrimidyl], act as close chemical analogs of highly unstable monomeric Py*TeCl and Pm*TeCl. The quasi‐planar zwitterionic structures of 1 and 2 have been studied by experimental (X‐ray diffraction, multinuclear NMR, IR and Raman spectroscopy) and theoretical (DFT and QTAIM) methods. Thus, a novel facile route to stabilize highly reactive Ar*TeCl species (Ar* = N‐functionalized aryl) by the addition of a hydrochloric acid molecule has been demonstrated. Two new stable T‐shaped tellurenyl chloride adducts, [HPy*]TeCl2 (1) and [HPm*]TeCl2 (2) [Py* = 2‐pyridyl, Pm* = 2‐(4,6‐dimethyl)pyrimidyl], act as close analogs of highly unstable monomeric Py*TeCl and Pm*TeCl. The quasi‐planar zwitterionic structures of 1 and 2 were studied by experimental and theoretical methods. Thus, a novel facile route to stabilize highly reactive Ar*TeCl species (Ar* = N‐functionalized aryl) by addition of an HCl molecule has been demonstrated.
