The first reported synthesis, characterization, and conformational analysis of the eight-membered germocin 2,2′-(4,6-di-1BuC6H2O)2GeMe2 (3) is described. The VT 1H NMR, 13C(1H) NMR, and crystallographic data of 3 is consistent with a boat-chair conformation for the ring in both solution and the solid state. The free energy of activation (ΔG299∗) for ring inversion is 55.6 kJ · mole−1 (13.3 cal · mole−1).
