Swrunary: Reaction of 2-lithiofuran or 1-methyl-2-lithiopyrrole with trialkylboranes leads to a borate salt. Subsequent treatment with an appropriate electrophile such as NCS leads to the 2alkylfuran or 1-methyl-2-alkylpyrrole. Electrophilic substitution is among the most important methods known fo
