摘要

Abstract A one-pot synthesis of various symmetrical and unsymmetrical 2-pyridyl-, 2-bromo- 5-pyridyl-, and 2, 5-dibromo-3-pyridyltellurium compounds has been carried out, at room temperature, by selective single bromine-magnesium exchange of 2-bromo-, 2, 5-dibromo- and 2, 3, 5-tribromopyridine, respectively, with isopropylmagnesium chloride. This exchange reaction gives the corresponding pyridylmagnesium chlorides, which, upon insertion of ...
