reaction is the Wittig-Horner reaction (1). ABSTRACT Georg Wittig was a German chemist and Nobel Prize winner in 1979 for the Wittig reaction (1). He was born in Berlin‚ on June 16‚ 1897‚ and died August 26‚ 1987 (1). Wittig discovered the route to alkenes through ylide molecules (1). Wittig was educated originally at Tubingen; Wittig spent periods at Braunschweig‚ Freigurg‚ back to Tubingen again before taking up the post as director of the organic chemistry department at Heidelberg (1). Wittig became

The Michael addition is a reaction named after Arthur Michael. Discovered in 1887‚ this is a carbon-carbon bond making reaction. The result of the Michael addition is a 1‚4 addition of a nucleophile to an alpha‚ beta-unsaturated carbonyl carbon compound. A 1‚4 addition is also commonly referred to as a conjugated addition. Another result of this reaction is a 1‚2 addition of a nucleophile. Some of the common attacking nucleophiles used in this reaction are enolates. Enolates‚ a negatively charged

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula
