containing from 1 to about 10 carbon atoms r1 r2 and r3 will typically be alkyl groups containing from 1 to about 4 carbon atoms or alkoxy groups containing from 1 to 4 carbon atoms it is preferred for r1 r2 and r3 to be methyl groups ch3 ethyl groups ch3 ch2 methoxy groups ch3 o u2014 or ethoxy groups ch3 ch2 o u2014 wherein x represents a neucleophile and wherein r1 r2 and r3 can be the same or different and represent alkyl groups aryl groups or alkoxy groups containing from 1 to about 10 carbon atoms can be reacted with the dilithium initiator in place of the halide compounds described above in such compounds the neucleophile will typically be selected from the group consisting of aldehydes ketones esters halides and acetals halides are typically preferred neucleophiles the alkylaminoaryl compounds that can be reacted with the dilithium compound are typically of the structural formula wherein r r u2032 and r u2033 can be the same or different wherein r is selected from the group consisting of hydrogen atoms alkyl groups aryl groups alkaryl groups and amino aryl groups and wherein r u2032 and r u2033 represent alkyl groups it is typically preferred for r u2032 and r u2033 to represent alkyl groups that contain from 1 to about 8 carbon atoms it is generally more preferred for r u2032 and r u2033 to represent alkyl groups that contain from 1 to about 4 carbon atoms such as methyl groups ethyl groups propyl groups and butyl groups highly preferred alkylaminoaryl compounds that can be utilized.
