A síntese one-pot de complexos diméricos de boro é descrita. Os compostos foram obtidos pela reação de bases de Schiff (ligantes tridentados) com ácido trans-β-fenilvinilborônico, ácido 3tiofeninoborônico e ácido metilborônico. A construção das estruturas diméricas é favorecida pela presença de ligações de coordenação N→B intramoleculares, resultando na formação de anéis heterociclicos de dez m...
