  The synthesis of a new, paramagnetic closo-[(8-(-CH2CH2O)2-1,2-C2B9H10)(1′,2′-C2B9H11)-3,3′-Fe]0 (3) is reported. This compound can serve as a versatile building block for construction of both anionic and zwitterionic derivatives, as exemplified by the synthesis of a series of compounds of general formula closo-[(8-X-(CH2CH2O)2-1,2-C2B9H10)(1′,2′-C2B9H11)-3,3′-Fe], bearing organic end groups (X = NC5H5

• Electrochemistry of Electron Transfer Probes. alpha-Aryloxyacetoveratrones and Implications for the Mechanism of Photo-yellowing of Pulp.

  Standard potentials (E degrees) of a series of substituted alpha-aryloxyacetoveratrone derivatives have been determined from a correlation of the C-13 NMR chemical shifts of the carbonyl group and a similar correlation (E degrees vs. C-13 NMR shifts) within a series of alpha-anilinoacetoveratrones. Using these potentials the rate constants for fragmentation of the radical anions were determined by digital simulation of the voltammetric waves. The rate contants for C-O cleavage in the radical anions correlate with the pK(a) of the corresponding phenols. The fragmentations are all in the activated region of a general free energy relationship for this class of compound (alpha=0.5). The standard potential and rate constant for fragmention of the alpha-guaiacoxyacetoveratrone radical anion also were determined. This species is a model compound for one of the lignin substructures. The implication of these results on the currently accepted mechanism for photoyellowing of lignin rich paper is discussed.
