Effects of a Sterically Demanding P-Aryl Substituent in Phosphole and 7-Phosphanorbornene Chemistry
The 2,4-di-tert-butyl-6-methylphenyl substituent was placed on phosphorus of a phosphole, causing restricted rotation about the P-C bond and flattening of the phosphorus pyramid. Electron delocalization was greater in this phosphole as a result of the flattening. The 7-phosphanorbornene with this su...

| Zusammenfassung: | The 2,4-di-tert-butyl-6-methylphenyl substituent was placed on phosphorus of a phosphole, causing restricted rotation about the P-C bond and flattening of the phosphorus pyramid. Electron delocalization was greater in this phosphole as a result of the flattening. The 7-phosphanorbornene with this substituent had the most deshielded
