摘　　要：Reaction of anion(phenoxo)functionalized-NHC predecessor[HO-3,5-di-C(CH3)3-C6H2-2-CH2{CH(NCHCHN)CH(CH3)2}]Cl with N-BuLi in molar ratio 1∶2 at the room temperature gives the first N-heterocyclic carbenes(NHC)benzyl migration product functionalized by phenoxo.The compound has been characterized by the 1HNMR and X-ray diffraction.The result show the crystal belongs to monoclinic system with a=10.8224(18),b=19.469(3),c=11.6658(18),α=90°,β=97.992(4)°,γ=90(11)°,V=2434.1(7)3,Z=2,Dc=1.109Mg/m3,μ=0.069 mm-1,F(000)=888.The reason for 1,2-benzyl migration is temperature,at the same time the mechanism of the reaction has been discussed in this article.Reaction of anion （phenoxo） functionalized-NHC predecessor [ HO-3,5 -di-C （ CH3 ） 3 -C6 H2-2-CH2 { CH （ NCHCHN ） CH （ CH3 ） 2 } ] Cl with N-BuLi in molar ratio 1：2 at the room temperature gives the first N-heterocyclic carbenes （NHC） benzyl migration product functionalized by phenoxo. The compound has been characterized by the ^1HNMR and X-ray diffraction. The result show the crystal belongs to monoclinic system with a = 10.8224（ 18）A,b = 19.469（3） A,c = 11. 6658（18） A,α =90°,β =97. 992（4）°,γ =90（ 11 ） ° ,V =2434.1 （7）A^3 ,Z =2 ,Dc = 1. 109Mg/m^3 ,μ =0.069 mm^-1 ,F（000） =888. The reason for 1,2-bemyl migration is temperature, at the same time the mechanism of the reaction has been discussed in this article.
