Nuclear magnetic resonance spectra of organogermanium compounds. Part 11. Synthesis and nuclear magnetic resonance spectra of tetramethyldigerma- and octamethyltetragerma-cycloalkanes
Abstract
Digermamacrocycles ranging from 10- to 22-membered rings and tetragermamacrocycles ranging from 20- to 44-membered rings have been prepared and their 13C and 73Ge NMR spectra determined. A preliminary experiment indicates that the germamacrocycles possess no anion transfer properties.
