Regioselective halogen-metal exchange reactions using isopropylmagnesium chloride were carried out on 3-substituted 1,2-dibromo arenes. Eleven examples are given. Georg Thieme Verlag Stuttgart.
Ortho-metalation of unprotected 3-bromo and 3-chlorobenzoic acids with hindered lithium dialkylamides
Gohier, Frederic,Mortier, Jacques
, p. 2030 - 2033 (2007/10/03)
Upon treatment of 3-chloro/bromobenzoic acids with hindered lithium dialkylamides (LDA or LTMP) at -50 °C, lithium 3-chloro/bromo-2-lithiobenzoates are generated. These dianions can be trapped as such to afford after electrophilic quenching a variety of s
