Web10 okt. 2024 · In 1955, Rolf Huisgen published a review in Angewandte Chemie on diazoalkane chemistry, and 63 years later, he was co-author of a state-of-the-art study of diazoalkane cycloadditions. In between, he created definitive articles on 1,3-dipolar cycloadditions (Huisgen reaction), the defining article on cycloadditions in general, and … WebIn a typical procedure, the crude diol prepared from diketone 1 (3.12 g, 17.9 mmol) was dissolved in anhyd CH 2 Cl 2 (250 mL), anhyd MgSO 4 (22.0 g. 0.18 mol) followed by TsOH·H 2 O (1.0 g, 5.26 mmol) were added, and the resulting mixture was vigorously stirred for 2 d at r.t.
