Freon matrices affected the nature of species stabilized upon the X-ray irradiation of frozen 1,7-dioxaspiro[5,5]undecane (DOSU)/CF3CCl3 or DOSU/CFCl3 solutions at 77 K. This manifested in the stabilization of a ring-closed DOSU radical cation (RC) w

The data on the structure and the features of the photochemical reactions for radical cations (RCs) derived from various oxiranes (epoxides) that can be stabilized in Freon matrices at 77 K are summarized. The nature of the RCs and the products of th

The classic version of aza-Wittig reactions, namely, reactions between phosphazenes and compounds with polar double bonds, is widely employed in organic synthesis to produce C=N bonds. However, only a limited number of aza-Wittig reactions between ph

Ring opening of donor–acceptor cyclopropanes with various N-nucleophiles provides a simple approach to 1,3-functionalized compounds that are useful building blocks in organic synthesis, especially in assembling various N-heterocycles, including nat

By employing EPR and UV/VIS spectroscopy and quantum chemical techniques, we demonstrated that the radical cations of cyclohexene oxide were stabilized upon radiolysis in freonic matrices at 77 K in their distorted form (with the C–C bond in the ox

It has been established that the photoinduced process observed in EPR and in optical absorption spectra for 1,4-dithiane radical cations in the CF3CCl3 matrix at 77 K can be ascribed to a “boat”—“twist boat” conformational transition.
