A [10,10]paracyclophane, 5,5,6,6,21,21,22,22-octamethyl-5,6,21,22- tetragerma[10.10]paracyclophane (4a), with two - R1R2GeGeR1R2- moieties in the center of two bridges, was prepared. An attempt to synthesize cyclophanes, 4b (R1=Me; R2=Ph) and 4c (R1=R2=Ph) was also made. The products were not analytically pure even after strenuous purification procedure to indicate that a double Wurtz coupling reaction is extremely difficult and necessarily accompanied by formation of polymeric by-products.
