1,2-Rearrangements of β-Nitrogen-Substituted (Porphyrinato)rhodium(III) Ethyls

(Porphyrinato)rhodium(III) ethyls containing β-nitrogen substituents have been showed to undergo clean, thermal 1,2-rearrangements into the α-nitrogen-substituted rhodium ethyls. The rates and the equilibrium positions were found to be dependent on the electronic nature of the N substituents. Complexes 1a−3a were characterized by X-ray crystallography.带有β位氮取代基的(卟啉合)铑(III)乙基配合物，已被证实可发生洁净的热诱导1,2重排反应，转化为α位氮取代的铑(III)乙基配合物。该反应的速率与平衡位置，均取决于氮取代基的电子性质。配合物1a~3a经X射线晶体衍射法（X-ray crystallography）完成表征。
