A number of hitherto unknown 1,1′-binaphthyl derivatives bearing silyl suubstituents at the 2,2′ positions have been prepared. The 2,2′-bis(dimethylsilyl)-1,1′-binaphthalene 2a is stable in the pure state, but it converts smoothly into the cyclic disiloxane 4a with water and acids or bases. The latter siloxane 4a can be converted back into the starting bishydrosilane 2a with lithium aluminim hydride
