Über galvinole und galvinoxyl-mehrspinsysteme—I : Eine neue metallorganische synthese von mono- und oligo-galvinolen

The synthesis of the so far unknown organometallic compound (2,6 - di - tert. - butyl - 4 - lithiumphenoxy) - trimethylsilane is most useful for the general introduction of the 3,5 - di - tert. - butyl - 4 - hydroxyphenyl group. Using the esters of aromatic mono-, di-, and tricarboxylic acids mono-, bis-, and tris-galvinoles are obtainable, while nitriles and dimethyl formamide are converted into ketones and the 3,5 - di - tert. - butyl - 4 - hydroxybenzaldehyde, respectively. In the present paper the experimental procedure and structure determination of the compounds in question are described.
