Abstract

Abstract A novel series of bicyclic organogermanium derivatives: 5-germaspiro [4.4] nona-2, 7-dienes have been prepared by reaction of 1, 1-dihalogermacyclopent-3-enes with the appropriate conjugated diene and an alkali metal in a suitable organic solvent. The best results were obtained by using 1, 1-dichlorogermacyclopentenes with isoprene or 2, 3- dimethylbutadiene and lithium in 5/1 ether/tetrahydrofuran. Except for 2, 3, 7, 8-tetramethyl ...
