Kurach, Pawel published the artcileOne-pot generation of lithium (lithiophenyl)trialkoxyborates from substituted dihalobenzenes (Hal = Br, I) and their derivatization with electrophiles, Synthetic Route of 849062-12-0, the publication is European Journal of Organic Chemistry (2008), 3171-3178, database is CAplus.
The simple one-pot approach to synthetically useful phenyl-trialkoxyborates bearing lithium at the Ph ring has been developed starting with 1,3- and 1,4-diiodobenzene, as well as several activated dibromobenzenes and bromoiodo-benzenes. The general sequence of transformations involves halogen-lithium exchange by using nBuLi and subsequent boronation with a trialkylborate. The resulting lithium (halophenyl)trialkoxyborates were then subjected to halogen-lithium exchange in situ with a second equivalent of nBuLi to give dianionic lithium (lithiophenyl)trialkoxyborates. Treatment with selected electrophiles afforded substituted arylboronic acids and/or their pinacol esters as final products in moderate-to-good yields.
