  Reactions of a dimetallated N,N′-dimethyl substituted porphyrinogen Sm(II) complex with a series of t-butyl substituted heteroalkynes affords a diverse range of reactivity. The phosphaalkyne t-BuCP gives a dinuclear Sm(III) P–P reductively coupled complex of (t-BuCPPC-t-Bu)2− featuring a new μ-η2(1,2-C,P) binding mode. In contrast, the nitrile aza analogue t-BuCN forms Sm(II) adducts that undergo reductive C–C bond cleavage at elevated temperatures to afford a trimeric Sm(III) cyanide (μ-CN−) complex. The isomeric isonitrile t-BuNC undergoes the related reductive C–N bond cleavage reactivity at milder temperatures, allowing the trapping of the tert-butyl fragment as a Sm(III) η2-iminoacyl (t-BuCN-t-Bu)− complex.

  二金属化的 N,Nâ²-二甲基取代的卟啉原 Sm(II) 复合物与一系列叔丁基取代的杂炔发生反应，产生了多种多样的反应性。膦炔类 t-BuCP 生成了双核 Sm(III) PâP 还原耦合复合物 (t-BuCPPC-t-Bu)2â，具有新的δ-δ-2(1,2-C,P) 结合模式。相比之下，腈基苯甲酰类似物 t-BuCN 形成的 Sm(II) 加合物在高温下会发生还原性 CâC 键裂解，生成三聚 Sm(III) 氰化物（δ-CNâ）复合物。异构体异腈 t-BuNC 在较温和的温度下会发生相关的还原性 CâN 键裂解反应，从而使叔丁基片段作为 Sm(III) δ-2-亚氨基酰（t-BuCN-t-Bu）â 复合物被捕获。

  strong structural resemblance to samarocene(III) alkyl complexes. The monomeric complexes are free of alkali metals, halides, and coordinating solvent. The methyl and (trimethylsilyl)methyl complexes have been characterized by NMR spectroscopy, X-ray crystal structure determinations, and elemental analyses. Initial reactivity studies highlight the low reactivity of the complexes.

  An eta(2)-bound cyclooctatetraenediyl lanthanide complex of an eta(5):eta(1):eta(5):eta(1)-bound modified porphyrinogen has been prepared, owing to the limited coordination site space at the Sm-III center. In contrast, when the auxiliary ligand is the smaller cyclopentadienyl ligand, eta(5) binding is achieved through distortion of the macrocycle, leading to a reduction in its hapticity to eta(5):eta(1):eta(1):eta(1) binding.
