Reaction of dioxoruthenium(VI) porphyrins [Ru(VI)(Por)O2] with arylimine HN=CPh2 in dichloromethane afforded bis(methyleneamido)ruthenium(IV) porphyrins [Ru(IV)(Por)(N=CPh2)2] for Por = 4-Cl-TPP and TMP; (methyleneamido)hydroxoruthenium(IV) porphyrins [Ru(IV)(Por)(N=CPh2)(OH)] for Por = TPP and TTP; and bis(arylimine)ruthenium(II) porphyrins [Ru(II)(Por)(HN=CPh2)2] for Por = 3,5-Cl2TPP and 3,5-(CF3)2TPP. In dichloromethane solution exposed to air, complex [Ru(II)(3,5-Cl2TPP)(HN=CPh2)2] underwent oxidative deprotonation to form [Ru(IV)(3,5-Cl2TPP)(N=CPh2)2]. The new ruthenium porphyrins were identified by 1H NMR, UV-vis, IR, and mass spectroscopy, along with elemental analysis. X-ray crystal structure determinations of [Ru(IV)(4-Cl-TPP)(N=CPh2)2], [Ru(IV)(TPP)(N=CPh2)(OH)], and [Ru(II)(3,5-(CF3)2TPP)(HN=CPh2)2] revealed the Ru-N(methyleneamido) or Ru-N(arylimine) distances of 1.897(5) A (average), 1.808(4) A, and 2.044(2) A (average), respectively.
在二氯甲烷中，二氧钌（VI）卟啉[Ru(VI)(Por)O₂]与芳基亚胺HN = CPh₂反应，对于Por = 4-Cl-TPP和TMP，生成双（亚甲基氨基）钌（IV）卟啉[Ru(IV)(Por)(N = CPh₂)₂]；对于Por = TPP和TTP，生成（亚甲基氨基）羟基钌（IV）卟啉[Ru(IV)(Por)(N = CPh₂)(OH)]；对于Por = 3,5-Cl₂TPP和3,5-(CF₃)₂TPP，生成双（芳基亚胺）钌（II）卟啉[Ru(II)(Por)(HN = CPh₂)₂]。在暴露于空气的二氯甲烷溶液中，配合物[Ru(II)(3,5-Cl₂TPP)(HN = CPh₂)₂]发生氧化去质子化反应，形成[Ru(IV)(3,5-Cl₂TPP)(N = CPh₂)₂]。通过¹H NMR、紫外可见光谱（UV-vis）、红外光谱（IR）、质谱以及元素分析对新的钌卟啉进行了鉴定。[Ru(IV)(4-Cl-TPP)(N = CPh₂)₂]、[Ru(IV)(TPP)(N = CPh₂)(OH)]和[Ru(II)(3,5-(CF₃)₂TPP)(HN = CPh₂)₂]的X射线晶体结构测定结果表明，Ru-N（亚甲基氨基）或Ru-N（芳基亚胺）的距离分别为1.897(5) Å（平均值）、1.808(4) Å和2.044(2) Å（平均值）。
