Chemically induced dynamic nuclear radical additions

Several lines of evidence indicate that the oxidative addition of RX to the electron-rich early-metal complex Cp2Zr(II)L2also occurs by a radical pathway initiated by electron transfer (Equation 7.8). - Zr(III) intermediates were observed by EPR, and evidence for effects of CIDNP (Chemically Induced Dynamic Nuclear Polarization) were observed in... [Pg.308]

Current abbreviations will be used BP for benzoyl peroxide, DTBP for di-/-butyl peroxide, AIBN for azo-bis(isobutyronitrile). In for initiation, esr for electron spin resonance, and cidnp for chemically induced dynamic nuclear polarization. Furthermore, we have chosen to adopt homogeneous abbreviations for the radicals discussed. The precursor radicals will be called A, generated from AH, AX,..., and the two possible radicals resulting from intramolecular addition will be called Cy (for cyclized) followed by a number for the size of the ring. [Pg.122]
