Abstract

Zusammenfassung Die reaktion zwischen Butyllithium und dem Tetraphenylester der Orthothiokohlensäure C (SC 6 H 5) 4 in Tetrahydrofuran bei− 70° führt zum metallierten Triphenylester der Orthothioameisensäure LiC (SC 6 H 5) 3 durch nukleophilen Angriff an Schwefel. Es bildet sich dabei zugleich Butylphenylsulfid C 4 H 9 SC 6 H 5. Alkylierung der Metallverbindung mit Alkyljodid oder Allybromid gelingt glatt, ebenso die Carboxylierung ...
