摘要
The title compound 2-(4-fluorophenylamino)-2-thiomethyl acetophe-none (C15H14FNOS, M. = 275. 34 ) was synthesized by the reaction of 2-hydroxy-2-thiomethyl acetohenone (abenzoylhemithioacetal ) with 4-fluoroaniline. The crystal ismonoclinic, space group P21/n. with unit cell constants a = 12. 434 (4 ), b = 6. 00l2(6), c=l8. 49l(2) A, β=100. 87(l)° Z = 4, V = 1355. O(5) A, D'= 1. 350g/cm3, μ(MoKa) = 2. 41 cm-l, F(000) = 576, R=0. 029, Rw.= 0. 041 for 14l2 ob-served reflections (I> 3σ(I) ). X-ray analysis reveals that the dihedral angle betweenplane l (C(l)~C(6), F, N ) and plane 2 (C(8)~C(14), O ) is 4. l8° and theC(7) -S bond is longer than normal single C-S bond.
