| Abstract: | EPR spectroscopy was used to study the rotational mobility and stannotropy dynamics of 3,6-di-tert-butyl-2-(chlorodimethylstannyl)oxyphenoxyl in viscous media. The correlation times for rotational motion of 3,6-di-tert-butyl-2-(triphenylstannyl)- and 3,6-di-tert-butyl-2-(chlorodimethylstannyl)oxyphenoxyls upon variation of the viscosity of the medium and temperature in a broad range. These times are related to each by a constant. A relationship was shown between the mobility of the medium and the stannotropy dynamics. A linear relationship was found between the time for intramolecular migration of the SnClMe2 fragment and rotational motion correlation time.For previous communication see [1].Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1535–1539, July, 1990. |
