| abstract | 1421356 Organo(alkali metal) compounds; halogenated acetals and ketals FIRESTONE TIRE & RUBBER CO 12 Dec 1973 [13 Dec 1972] 57668/73 Headings C2C and C2J [Also in Division C3] Organoalkali metal compounds containing an acetal or ketal group, suitable as polymerization initiators, are obtained by metalation of the corresponding halogenated acetals or ketals, the products being of the formulµ MR 1 .O.CHR 3 - (OR 2 ) or MR 1 .O.CR 3 R 4 (OR 2 ) where M is an alkali metal (K, Na or Li), R<SP>1</SP> is alkylene, cycloalkylene or phenylene, and R 2 , R 3 and R 4 are hydrocarbyl groups. Many such products are listed and examples refer to Li(CH 2 ) 2 .O.CH(CH 3 )(OC 2 H 5 ), LiC 6 H 4 .O.CH(CH 3 )(OC 2 H 5 ), Li(C 6 H 12 ).OCH(CH 3 )(OC 2 H 5 ), and Li(CH 2 ) 3 .O.C(CH 3 ) 2 .(OC 2 H 5 ). The halogenated acetal or ketal precursors are obtained by reaction of an unsaturated ether and a halogen-containing alcohol in the presence of an acid. Examples refer to reacting ethylvinylether and 3-bromopropanol to give ethyl vinyl ether and 6-chlorohexanol to give Cl(CH 2 ) 6 .O.CH(CH 3 )(OC 2 H 5 ), p - iodophenol and ethyl vinyl ether to give and 1-methylethenylethylether and 3-bromopropanol to give |
