A laminate includes a copper wiring layer (20) provided over a semiconductor layer and having a specific pattern, a protective layer (30) formed of a polybenzoxazole resin layer provided on the copper wiring layer (20), and an insulating layer (40) provided on the protective layer.
A novel Pd-catalyzed C-H functionalization reaction was developed to construct a quaternary carbon center with high yield. This reaction provides an efficient method for the synthesis of 9,9'-diarylfluorenes by direct arylation of monoarylfluorene.
