Selective synthesis of tetraarylgermanes and triarylgermanium halides

A series of novel and previously published tetraarylgermanes aryl4Ge (aryl 1⁄4 m-tolyl, 3,4-xylyl, 3,5-xylyl, 2-naphthyl) and triarylgermanium halides aryl3GeX (aryl 1⁄4 o-tolyl, 2,4-xylyl, 2,5-xylyl, 2,6-xylyl, 1- naphthyl, 2,4,6-mesityl, X 1⁄4 Cl, Br) were synthesized and characterized. All solids were investigated using single crystal X-ray diffractometry in order to elucidate the molecular structures. Effects of the substitution pattern of the aryl residue employed have been studied in terms of the impact on the product formation.
