Heinrich Emil Albert Knoevenagel (German pronunciation: [ˈhaɪ̯nʁɪç ˈeːmiːl ˈalbɛʁt ˈknøːvənaːɡl̩]; 18 June 1865 – 11 August 1921) was the German chemist who established the Knoevenagel condensation reaction. The Knoevenagel condensation reaction of benzaldehydes with nitroalkanes is a classic general method for the preparation of nitroalkenes, which are very valuable synthetic intermediates.
