在MS 4A存在下，用催化量的Pd（dba）（2）-t-Bu 3 P（dba =二亚苄基丙酮）和三乙胺处理环庚三烯基甲基酮O-五氟苯甲肟，通过肟氧化加成到Pd（0）络合物上产生的亚烷基氨基钯（II）中间体，合成各种1-氮杂奥。
Various 1-azaazulenes are synthesized from cycloheptatrienylmethyl ketone O-pentafluorobenzoyloximes by treatment,with a catalytic amount of Pd(dba)(2)-t-Bu3P (dba = dibenzylideneacetone) and triethylamine in the presence of MS 4A via alkylideneaminopalladium(II) intermediates generated by oxidative addition of the oximes to a Pd(0) complex.
