Synthesis and crystal structure of 2-(Dichloromethyl)-2-(4-nitrophenyl)-1,3-dioxane

A new compound,2-dichloromethyl-2-p-nitrophenyl-1,3-dioxane,was synthesized and characterized. the crystal structure of the title compound (c11h11cl2no4,m r = 292.11) has been determined by single-crystal x-ray diffraction. the crystal is of monoclinic,space group p 2 1 / c with a = 11.013(2) å,b = 14.653(3) å,c = 7.8693(16) å,α = 90 °,β = 97.06(3)°,γ = 90 °,v = 1260.3(4) å 3,z = 4,f(000) = 600,d c = 1.540 mg/cm3,the final r 1 = 0.0508,and ω r 2 = 0.1072 for observed reflections with i > 2 σ i. a total of 12162 reflections were collected,of which 2867 were unique (r i n t = 0.06999). © 2013 fei ye et al.
