Abstract:The title compound has been synthesized via a green microwave -assisted one -pot two -step re- action of 1 - isothiocyanato - 4 - methylbenzene with 2 - cyanoacetamide and cyclobutanone in DMF, and its structure was determined by monocrystalline X - ray diffraction. The crystal is triclinic, space group P-1 witha =6. 4434(6) nm, b = 11. 2490(12) nm, c = 11. 3527(14) nm, α = 115. 042(2)°, β= 104.481(10)°, γ= 94.405(10)°, Mr= 285.36, V= 706.01(13) nm3, Dc= 1.342 g/cm3, Z= 2,μ(MoK,) = 0. 228 mm-1, F(000) = 300. The structure was solved by direct methods and refined by the full - matrix method of least - squares to the final R = 0. 051 8, Rw = 0. 122 6.
Keywords:microwave synthesis  crystal structure  multi -component reaction
