title: Catalyst-Free and Regioconvergent Substitution Reactions of Bromothiophenes with a BH3-Substituted Phosphide Anion.
abstract: A range of bromothiophenes reacted with lithium boranato(tert-butyl)methylphosphide in the absence of transition-metal catalysts under mild conditions to provide the same 2,5-disubstituted and 2-monosubstituted products regardless of the substitution patterns of the starting bromothiophenes.
