Dispersion Energy Enforced Dimerization of a Cyclic Disilylated Plumbylene.

By reaction of 1,4-dipotassio-1,1,4,4-tetrakis(trimethylsilyl)tetramethyltetrasilane with PbBr2 in the presence of triethylphosphine a base adduct of a cyclic disilylated plumbylene could be obtained. Phosphine abstraction with B(CF) led to formation of a base-free plumbylene dimer, which features a...
