Notes:
The effects of the nature of the electrodes (sacrificial anode and cathode) and of the solvent on the electroreduction of di-n-hexyldichlorogermane have been investigated. Several sacrificial anodes (magnesium, zinc and aluminium) and cathodes, including stainless steel, magnesium and aluminium, have been used in THF containing LiClO4. Monomodal and polymodal poly(di-n-hexylgermanes) were obtained with Al/Al and Mg/Mg electrode pairs, but the polymer yield was about twice as high with Al/Al (64%) as with Mg/Mg (30%). Various solvents (tetrahydrofuran, hexamethylphosphorotriamide, N,N-dimethylacetamide, acetonitrile and dimethylformamide) with LiClO4 have been used as electrolytic media. Monomodal PDHG with a relatively narrow molecular weight distribution ([M¯]w/[M¯]n=1.6) was obtained only in THF/HMPA with Al/stainless steel electrodes. © 1997 John Wiley & Sons, Ltd.
