T-buoh mechanism
WebIt crystallizes as a tetrameric cubane-type cluster. It crystallises from tetrahydrofuran / pentane at −20°C as [tBuOK·tBuOH] ∞, which consists of straight chains linked by hydrogen bonding. Sublimation of [tBuOK·tBuOH] ∞ affords the tetramer [tBuOK] 4, which adopts a cubane-like structure. WebDec 21, 2024 · Demethylation of levulinic acid (1) with I 2 and t-BuOK in t-BuOH. To a stirred solution of t-BuOK (95 mg, 0.85 mmol) in distilled t-BuOH (1.4 mL) was added I 2 (72 mg, 0.28 mmol) and the mixture ...
