    • Synthesis of 4: in the glovebox. a mixture of, Cp IIIDy(BH4, 100 mg, 156 μmol) and [18]crown-6 (42 mg, 156 μmol) was placed in a centrifugation tube and dissolved in cyclohexane (8 mL, After addition of KC8 (42 mg, 312 μmol) the reaction mixture was shaken, immediately giving a dark red solution from which the product precipitated over 24 h at room temperature. The supernatant was removed, and the precipitate was taken up in toluene (15 mL, After centrifugation, the solution was evaporated, yielding pure 4 as a dark red powder (95 mg, 100 μmol, 64% yield, 1H NMR (300 MHz. toluene-d8, δ(ppm) 343 (br s, w1/2, 3 kHz, tBu, 133 (br s, w1/2, 3 kHz, tBu, 49 (br s, w1/2, 2 kHz, 18]crown-6, 178br s, w1/2, 3 kHz, tBu, Crystals suitable for X-ray diffractometry were obtained from toluene at -30°C
