Organophosphorus Compounds, 51. - Phosphatriafulvenes - Phosphaalkenes with Inverse Electron Density

Peterson olefination of the sterically hindered cyclopropenones 1 with the lithium phosphides 2 yields the so far unknown phosphatriafulvenes 3 and 4, which possess inverse electron densities.They are characterized by transition metal complex formation (-

PHOSPHATRIAFULVENES - PHOSPHAALKENES WITH INVERSE ELECTRON DENSITY

The phosphatriafulvenes 3a,b, accessible from the cyclopropenone 1 and the lithium phosphides 2, possess inverse electron density as indicated by structure B; this can also be deduced from ab initio calculations.In accord with the electronic structure, me
