Notes Amines and Amides General Structures: 1 ° amine 2 ° amine 3 ° amine Amide N H H N R H N R R N H C H O Nomenclature: A point of concession from the IUPAC organization is that the most popular and useful nomenclature system for amines is not their own. Instead the Chemical Abstract, CA format is the most common and has been approved for use by IUPAC. Amines: Chemical Abstract format 1. count the carbons in the longest chain containing the amine 2. drop the –e ending for the parent name and add –amine 3. for a secondary amine an N prefixes the compound giving the shorter carbon chain its side chain prefix name 4. for a tertiary amine an N,N prefixes the compound giving the two shorter carbon chains their side chain prefix names Structural Formula N H C H H H H N CH 3 C H C H H H H H N CH 3 C CH 3 C H H H H H Condensed Structural Formula CH 3 NH 2 CH 3 CH 2 NHCH 3 CH 3 CH 2 N(CH 3 ) 2 CA format methanamine N-methylethanamine N,N-dimethylethanamine IUPAC 1. count the carbons in the longest chain containing the amine 2. add the prefix amino to the parent carbon chain name 3. assign the amino carrying carbon the lowest number possible 4. for a secondary amine an N prefixes the compound giving the shorter carbon chain its side chain prefix name 5. for a tertiary amine an N,N prefixes the compound giving the two shorter carbon chains their side chain prefix names Structural Formula N H C H H H H N H C H C H H H H H C CH 3 C H C H H H H H NH 2 N CH 3 C H C H H H H H Condensed Structural Formula CH 3 NH 2 CH 3 CH 2 NH 2 CH 3 CH 2 CHNH 2 CH 3 CH 3 CH 2 NHCH 3 IUPAC aminomethane aminoethane 2-aminobutane N-methylaminoethane
