Synthesis and Characterization of Phenoxo Functionalized N-Heterocyclic Carbene Complexes of Silver

利用4,6-tBu2-1-(HO)C6H2CH2Br与甲基咪唑反应合成了芳氧功能化的氮杂环卡宾前体[HO-4,6-tBu2-C6H2-2-CH2{CH(NCHCHN)CH3}]Br.然后,在60℃条件下以CH2Cl2作溶剂,将该前体与Ag2O反应合成了新的芳氧功能化的氮杂环卡宾银配合物Ag[O-4,6tBu-C6H2-2-CH2{CH(NCHCHN)CH3}].配合物进行红外光谱表征.

[ HO -4,6 - t Bu2 - C6 H2 -2 - CH2 { CH （NCHCHN） CH3} ] Br has been synthesized by the reaction of 4,6 - t Bu2 - 1 - （HO） C6 H2 CH2 Br with methyl - imidazole. Then, phenoxo functionalized - NHC complexes of Ag[ O- 4,6tBu -CsH2 -2 -CH/t CH（NCHCHN） CH3} ] has also been synthesized by the reflux reaction of Ag20 with the predecessor in CHEC12 solution at 60oC. All the compounds have been characterized by the infrared spectrometry and melting point. The results indicate the target compound has been synthesized. The special data of the target compound is as follow： IR： 3419.56cm-1 , 3001.03cm-1 , 2914.2gcm-I , 1647. 10cm-1 , 1409.87cm-1, 705.90cm-1 ; UV： λ = 235nm. λ= 285nm.
