摘要
Reaction of 2,4-di-Eert-butyl-phenol,ethylenediamine and formaldehyde （37% solution in water）in 2:1:5molar ratio in methanol afforded the 1,2-bis[3-（6,8-di-tert-butyl-3,4-dihydro-2[H]-1,3-benzoxazine）-yl]ethane in high yields.This compound was fully characterized by elemental analysis,1H NMR,MS,and IR spectroscopies.The crystal structure of the title compound was determined by X-ray diffraction method.It crystallizes in triclinic,space group P（1）,a=0.5727（2）,b=0.9268（3）,c=1.4666（4）nm,a=88.12（1）°,β=88.54（1）°,γ=80.82（1）°,V=0.7679（4）nm3,Z=1,DC=1.126Mg·m-3,F（000）=286,μ（MoKα）=0.69cm-1,R=0.048,wR=0.140.This compound had a centrosymmetrical structure.
