Chemically induced dynamic disproportionation

Kaptein R and Oosterhoff J L 1969 Chemically Induced dynamic nuclear polarization III (anomalous multiplets of radical coupling and disproportionation products) Chem. Phys. Lett. 4 214-16... [Pg.1618]

There is considerable agreement that the formation of Grignard reagents involves intermediate radicals. Evidence includes the trapping of intermediates by radical traps, CIDNP (chemically induced dynamic nuclear polarization) observations, and the occurrence of characteristic radical reactions (equation 6) such as disproportionation,...

CIDNP (chemically induced dynamic nuclear polarization) Non-Boltzmann nuclear spin state distribution produced in thermal or photochemical reactions, usually from colligation and diffusion, or disproportionation of radical pairs, and detected by nuclear magnetic resonance spectroscopy by enhanced absorption or emission signals.
