| titleOfInvention | Process of making protected aminofunctionalized polymerization initiators |
| abstract | A process for making amine-functionalized compounds comprising reacting one or more omega-tertiary-amino-1-haloalkanes of formula (R<1>)(R<2>)N-Z-X wherein: Z is an optionally substituted straight or branched chain hydrocarbon group; R<1>, R<2> are protecting groups selected from alkyl, aralkyl, allyl, or R<1>, R<2> together form an optionally substituted benzopyrrolidine ring; X is halogen; with an alkali metal in an alkane, cycloalkane, or aromatic solvent or mixtures thereof, to form compounds of formula (R<1>)(R<2>)N-Z-M wherein M is an alkali metal. The compounds of formula (R<1>)(R<2>)N-Z-M may be chain extended by reacting with one or more unsaturated organic compounds to give a compound of formula (R<1>)(R<2>)N-Z-Qn-M wherein Q is a saturated or unsaturated hydrocarbyl group wherein: n is 0-5. The preferred alkali metal is lithium and the preferred halogen is chlorine. Preferably the process involves the preaparation of 3-[N,N-dibenzylamino]-1-propyllithium and 3-[(N-benzyl-N-methyl)amino]-1-propyllithium. |
