Meoh h+ reaction
Web7 jan. 2015 · Compound 2 (5 mmol) was dissolved in MeOH (20 mL) and added dropwise to a mixture of ethylenediamine (22.3 g, 25 mL) and MeOH (50 mL) cooled to 0 °C. The reaction was equilibrated at room temperature and stirred for 5 days. The solvent was evaporated to dryness and then the residue was mixed with n-butanol (20 mL) and … WebThis is an electrophilic addition reaction. In Step 1, a hydronium or oxonium ion is attacked by the π bond. In Step 2, the alcohol attacks the carbocation and forms an oxonium ion. In Step 3, the alcohol deprotonates the oxonium ion to form the ether. Here’s a video on the addition of alcohols to alkenes. Ernest Z. · 2 · Dec 13 2014 Questions
