metal in ether. The yield of organometallic compound (determined by the titration of an aliquot with standard acid)* was in the range 85-95% in various preparations. Other aryllithium compounds prepared in this work and roquinoline. Addition of the aryllithium to 6- the yield'obtained were p-diethylaminophenyl-(84%), chloroquinoline followed by hydrolysis of the No-dimethylaminophenyl-(92%) and m-dimethylaminophenyl-(94%). s lithio ...
