Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

Unsaturated Hydrocarbons Unsaturated hydrocarbons Have fewer hydrogen atoms attached to the carbon chain than alkanes. Are alkenes with double bonds. Are alkynes with triple bonds. 1 Structure of Alkenes Alkenes (and alkynes) are unsaturated hydrocarbons Alkenes have one or more double bonds The two bonds in a double bond are different: - one bond is a sigma () bond; these are cylindrical in shape and are very strong - the other is a pi (π) bond; these involve sideways overlap of

THEORY: The Diels-Alder cycloaddition reaction was discovered by Otto Diels and Kurt Alder and is very useful in the synthesis of polycyclic compounds. The Diels-Alder reaction can be described as: [4+2] cycloaddition- a diene with 4 π electrons + 2π electrons from the dienophile; a pericyclic concerted reaction- meaning the reaction occurs in a single step (no intermediates) and involves a cyclic redistribution of bonding electrons. In order for a Diels-Alder reaction to take place

Chapter 2 21. An amino acid having the constitution shown has been isolated from horse chestnuts. It is configurationally related to L-proline and has the R configuration at C-3. Write a stereochemically correct representation for this compound. The addition of carbene by the cuprous chloride catalyzed the decomposition of diazomethane to 3‚4-dehydro-l-proline‚ which led to a combination of cis-3‚4-methylene-l-proline and trans-3‚4-methylene-l-proline in a proportion of 1:3.5. In addition‚ the
