The reaction of bis[bis(trimethylsilyl)methyl]-germylene (1) with N-(a
zidosilyl)germanimines 3a,b at room temperature gave bis(germanimines)
4a,b in quantitative yield whose structures have been confirmed by si
ngle-crystal X-ray diffraction. The photolysis of 4a gave the cyclic s
ilanimine 6 as an unexpected product.
