    • To a solution of LAl[C(O)C(SiMe3)C(SiMe3, 0.13 g, 0.20 mmol) in n-hexane (10 mL) was added a solution of water (1.8 μL, 0.10 mmol) in toluene (2 mL) at -78 °C. The mixture was warmed to room temperature. All volatiles were removed under vacuum, and the remaining solid was crystallized from n-hexane at -20 °C to yield 2 as yellow crystals (0.05 g, 59, Anal.
