• The Wittig modified Hofmann elimination goes through the same Ei mechanism, but instead of using silver oxide and water as base, the Wittig modification uses strong bases like alkylithiums or KNH2/liquid NH3.
• In 2002, a specific type of blackberry was named after Rüdiger Wittig: "Rubus wittigianus".
