Table 3. Light-driven azetidine formation mediated by UiO-68[Au1]4.5%.a.
Conditions: reactions were performed with 0.1 mmol of 3a–3f (used as mixtures of E/Z oxime or hydrazone isomers) and 5 mg of UiO-68[Au1]4.5% in MeCN (2 mL) at room temperature under argon and 410 nm irradiation for 0.5–2 h; product yields and diastereomeric ratios (d.r.) were determined by 1H NMR analysis from the crude reaction mixture using chlorodiphenylmethane as an internal standard. The single-crystal structure of product 4f is presented.
