Photochemical generation of chlorine-substituted digermenes and their rearrangement to germylgermylenes
Photolysis of cis, trans-1,2,3-trichloro-1,2,3-tris(tri-tert-butylsilyl)cyclotrigermane and trans-1,2-dichloro-3-methyl-1,2,3-tris(tri-tert-butylsilyl)cyclotrigerma ne in the presence of triethylsilane yielded products arising from a germylgermylene, which is formed by the 1,2-chlorine migration on digermenes.
