Method for attachment of alkyl groups on a chain carrying a functional group CARBONACEOUS

A METHOD TO FIX ON A CHAIN ​​CARBON BEARING FUNCTIONAL GROUPS CHOOSING BETWEEN THE RADICALS NITRILE, CARBOXYL, REMAINS OF ALKYL CARBOXYLIC ESTERS OR LINEAR BRANCHED 1 TO 5 CARBON ATOMS AND TERTIARY AMIDE FORM CO N ( R) R REPRESENTING A RADICAL ALKYL LINEAR 1 TO 3 CARBON ATOMS AND WITH ALSO AT LEAST ONE PROTON IN ALPHA POSITION IN RELATION TO THIS GROUP FUNCTIONAL AT LEAST ONE SUBSTITUTED FOR CHOOSING BETWEEN THE RADICALS ALKYL LINEAR OR bRANCHED 1 TO 12 CARBON ATOMS, THE aLKYL rADICALS AND RADICAL cycloalkyls WHERE THE REST aLKYL ACCOUNT 1 TO 4 CARBON ATOMS, PROCESS CHARACTERIZED BY IN A FIRST STAGE, WE DO rEACT ON THIS CHAIN ​​BASE COMPLEX FORMED BY A MIXTURE A amide ALKALI METAL AND A alkali alcoholate SUSPENDED IN ORGANIC SOLVENT ANHYDROUS, SUCH FORMING temporarily a carbanion, THEN IN A SECOND STAGE, WE DO rEACT ON THIS carbanion SOLUT ION IN ORGANIC SOLVENT ANHYDROUS AN ALKYL HALIDE EQUAL TO THE PLACE TO BE FIXED, THE TERM "ALKYL" HERE ALSO COVERING THE RADICALS aralkyl, and cycloalkyl CONSIDERED ABOVE.
