| 摘 要： | A novel compound of 10-(3,4-dichlorophenymethylidyne)-9,10-dihydrofluorene (C20H12Cl2, Mr = 323.20) was synthesized via Knoevenagel reaction under microwave irradiation (500 w) within short reaction time (8 min), giving a high yield of product (87%). Its structure was determined by IR, 1H NMR, MS, elemental analysis and X-ray diffraction. The crystal of the new compound is of monoclinic system, space group P21/c with a = 12.8781(13), b = 16.5067(16), c = 7.4656(7), β = 103.567(2)o, V = 1542.7(3)3, Z = 4, Dc = 1.392 g/cm3, μ = 0.413 mm-1, F(000) = 664, R = 0.0569 and wR = 0.1342 for 3355 observed reflections with I > 2σ(I). The crystal structure involves a conjugated system which shows an olefin structure.
