ChemInform Abstract: REACTIONS OF PHOSPHONIUM YLIDES WITH 9‐FLUORENETHIONE

Synthesis and fluorescence properties of carbazole and fluorene-based compounds

“…9-(4-Iodobenzylidene)-9H-fluorene (1) [22] Diethyl 4-iodobenzylphosphonate (0.35 g, 1 mmol) and 9H-fluoren-9-one (0.21 g, 1.2 mmol) were dissolved in 30 mL dry tetrahydrofuran. After the reaction mixture was heated to reflux, solid potassium tert-butoxide (0.24 g, 2 mmol) was added gradually.…”
