Reactions of 2,2-dibromocyclopropyl carboxylic acids with methyllithium

For reactions of 2,2-dibromocyclopropyl carboxylic acids with methyllithium, the course reaction depends mainly on the position of the carboxyl group.When the COOH group is directly attached to the gem-dibromocyclopropane ring MeLi generally attacks the gem-dibromo moiety and gives the corresponding monobromocyclopropane as the principal product.When the reaction is performed above -80 deg C the monobromides are formed stereospecifically in the trans configuration.The highest yields, as high as 80-90percent, are obtained 0 deg C.When the carboxyl group is not directly attached to the cyclopropane ring most of the MeLi is consumed in an acid-base reaction with the COOH group.
