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.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%）.
