✦ Synopsis

Laser-controlled bimolecular isotopic exchange reactions in bromine leading to alterations in natural isotopic abundance ratios have been directly observed using lasermodulated molecular beams and mass analysis. Several instances of selective excitation and subsequent rapid isotope exchange are observed within the 7 GHz gain curve of the exciting 514.5 nm line of an argon-ion laser. These exchange processes are attributed to the direct photochemical participation of excited molecular states in the B3n& system of Brp.

## Abstract We have shown previously that iodosylbenzene–iron(III) porphyrin intermediates (2) are generated in the reactions of oxoiron(IV) porphyrin π‐cation radicals (1) and iodobenzene (PhI), that 1 and 2 are at equilibrium in the presence of PhI, and that the epoxidation of olefins by 2 afford
