Structure of Diels-Alder Adduct of Phenylated Germole and 1, 4-Epoxy-1, 4-dihydronaphthalene Revisited

High pressure synthesis of Diels-Alder adduct of 1, 1-dimetyl-2, 3, 4, 5-tetraphenylgermole and 6, 7-dibromo-1, 4-epoxy-1, 4-dihydronaphthalene is described. The X-ray crystallography analysis of the so obtained adduct indicated that the adduct has exo, endo- structure in agreement with our earlier proposal for the stereochemistry of the structurally related germa analogon, 11, 11-dimethyl-9, 10-epoxy-1, 4-germa-1, 2, 3, 4-tetraphenyl-1, 4, 4a, 9, 9a, 10-hexahydroanthracene based on NMR analysis.
