Witrynaderivatives from various nitriles and sodium azide (NaN3) via [3+2] cycloaddition reaction using B(C6F5)3 as a catalyst. The present synthetic method displayed significant advantages such as low catalyst loading, mild reaction conditions, low toxicity, easy work-up, high yields and compatibility with other functional groups. WitrynaWith hydrogen bromide In water; toluene for 3 h; Reflux. To a stirred solution of dodecane-1,12-diol (8.365 g, 42.75 mmol), 48percent HBr in water (9.7 ml, 85.50 mmol) and toluene (120 ml) were added and the reaction mixture refluxed for 3 h. The reaction mixture was then concentrated, the crude compound was dissolved in DCM (150 ml), …
