Platt gemacht : Die Addition von PhCCH an Ar′GaGaAr′ (Ar′=2,6‐(2,6‐ i Pr 2 C 6 H 3 ) 2 C 6 H 3 ) führt zu dem 1,4‐Digallacyclohexadien [{Ar′GaC(Ph)CH} 2 ] ( 1 ), das bei der Reduktion mit Kalium in das 1,4‐Digallatabenzol‐Dianion [Ar′GaC(Ph)CH] 2 2− ( 2 ) übergeht (siehe Schema; C grau, Ga grün, K blau). Strukturparameter, Dichtefunktionalrechnungen und 1 H‐NMR‐spektroskopische Daten belegen den aromatischen Charakter von 2 .
