Abstract

Halogen-lithium interchange between (+)-(S)-l-bromo-l-methyl-2, 2-diphenylcyclopropane and n-butyllithium produced l-methyl-2, 2-diphenylcyclopropyllithium which on treatment with carbon dioxide, bromine, and iodine yielded products in ahich the configuration as well as the optical activity had been completely retained? io effect on the optical results could be found on varying the temperature, solvent, or reaction time, The lithium derivative bas ...
