Reductive coupling reactions of dihalogenogermanes with magnesium and magnesium bromide: simple preparation of cyclotrigermanes and cyclotetragermanes
Abstract
The reactions of various dihalogenogermanes with Mg and MgBr2 in tetrahydrofuran produce the corresponding cyclotrigermanes and cyclotetragermanes; the ring size of the products depends on the steric bulk of substituents on germanium.
