Novel 1,3-dialkylperhydrobenzimidazolinium chloride salts were prepared as precursors of N-heterocyclic carbenes 3a-e by reacting N,N’-dialkylcyclohexandiamine, triethyl orthoformate and ammonium chloride. The salts were characterized spectroscopically and the complexes formed in situ from Pd(OAc)2 and 3 have been tested as catalysts in homogenous Heck and Suzuki reactions.
合成了1,3-二烷基氢化苯并咪唑鎓氯盐,作为N-杂环卡宾3a-e的前驱体,反应物为N,N’-二烷基环己烷二胺、三乙基邻甲酸酯和氯化铵。这些盐通过光谱学方法进行了表征,并且由Pd(OAc)2和3原位形成的络合物被测试作为均相Heck和铃木反应的催化剂。
