19017 Alkyl Halides and AminesWith CO2 (Carbonation of Grignard Reagents, RMgX)NUCLEOPHILIC ADDITION OF RMg X TO CARBON DIOXIDEStep 1:The nucleophilic C in the Grignard reagent adds to the electrophilic C inthe polar carbonyl group, electrons from the C=O move to the electronegativeO creating an intermediate magnesium carboxylate complex.Step 2:This is the work-up step, a simple acid/base reaction. Protonation of thecarboxylate oxygen creates the carboxylic acid product from the intermediatecomplex.Quick Quiz1. What are organometallic compounds?2. Define protonation.3. What is formula of organolithium?4. How does RMgX reacts with CO2?5. Write the formula of Grignard Reagent.17.3 AMINES17.3.1 Nomenclature:1. Common System of NamingThe common names of amines are written by adding the suffix-amine to the name of alkylor aryl radicals.CH 3 CH 2 NH 2Ethyl amineCH 3 (CH 2 ) 3 CHCH 3NH 2Sec-hexyl amCH 3CHCH 3Iso-hexyl amine(CH 2 ) 3 NH 2 (a primary amine)CH 3CH 3NHDimethyl amine (a sec-amine
