Notes:
The first phosphines based on the benzo-7-phosphanorbornene system have been prepared and found to have extremely deshielded 31P nuclei. The phosphine with a P-tert-butyl group gives the most downfield value (δ +152.5) ever recorded for a tertiary phosphine. The lone-pair orientation in phosphines controls the magnitude of 2J (PC) and 3J (PC), and these effects were used to determine stereochemical features of the phosphines. These compounds were formed by HSiCl3—pyridine reduction of the Diels - Alder adducts of isophosphindole oxides with norbornadiene. 13C NMR was also used to confirm the assignment of these phosphine oxides.
