The addition of a variety of electrophiles to the semicyclic double bond of 1 and 4 has been studied. The anti/syn-product ratios show that the=inter&ztion between the Walsh-and n-orbitals causes only small selectivities. Photoelectron spectra revealed a sizeable (H.. = -0.338) through space interac
