Investigations of the Kocheshkov redistribution reaction were performed on the six fold coordinated tin(IV) atom using the axially coordinated Sn(IV) meso-tetra-phenylporphyrin system with axially trans di-chloro and trans di-acetylido substituted derivatives. The immobile four dentate porphyrin ligand enables the detailed investigation of these typically complex reaction systems on higher coordinated tin(IV) species. The thermally activated reaction displays an equilibrium. Further on, a series of axial unsymmetrically substituted Sn(IV) porphyrins are selectively synthesized and described.

六价配位Sn（IV）原子上的再分布反应和对轴向不对称取代的Sn（IV）卟啉的反应

使用具有轴向反式二氯和反式二乙酰基取代衍生物的轴向配位的Sn（IV）内消旋四苯基卟啉体系对六倍配位的锡（IV）原子进行了Kocheshkov重分布反应的研究。固定的四齿卟啉配体是固定的，可以对较高配位的锡（IV）物种上这些典型的复杂反应系统进行详细研究。热活化反应显示出平衡。进一步地，选择性地合成和描述了一系列轴向不对称取代的Sn（IV）卟啉。
