Phosphorus-nitrogen compounds- Part 50 : correlations between structural parameters for cylophosphazene derivatives containing ferrocenyl pendant arm s
Structural parameters derived from 11 types of the ferrocenyl cyclophosphazene derivatives with 5- to 7-membered spiro-rings introduced to the literature from our research group were studied and compared with each other.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:The results of a systematic study of spiro-cyclotri/tetraphosphazenes with ferrocenyl pendant arm on the basis of correlation between structural parameters were presented.
📊
Key Findings & Data:The main parameters were obtained from Xray crystallography and 31 P NMR results in order to investigate the relationship between the δ P$_{spiro}$ shift values and endocyclic and exocyclic NPN bond angles, and electron density transfer parameters.
💡
Conclusion & Impact:Structural parameters derived from 11 types of the ferrocenyl cyclophosphazene derivatives with 5- to 7-membered spiro-rings introduced to the literature from our research group were studied and compared with each other.
