[摘要]:Selective monolithiation of 2,2'-dibromobiphenyl, 4,4'-dibromobiphenyl, 2,7-dibromo-9,9-dioctylfluorene, 2,2'-dibromo-1,1'-binaphthyl, and 5,5'-dibromo-2,2'-bithiophene, with 1 equiv of butyllithium followed by reaction with electrophiles was achieved using a microflow system by virtue of fast micromixing and precise temp. control. Sequential introduction of two different electrophiles based on this method was also achieved using a microflow system composed of four micromixers and four microtube reactors. |
