  7. Synthesis and kinetic studies of tricyclic phosphates and phosphonates: Effect of phosphorus-oxide stereochemistry on allylic rearrangements

    … In this work, kinetic studies are reported on tricyclic phosphates and phosphonates which were prepared from 11 and 12 step syntheses. First order rate constants for solvolysis (k$\sb{\rm s}$) and loss of optical activity (k$\sb\alpha$) were measured for 12a and 12b under solvolytic conditions …
