| Abstract: | We have successfully characterized by EPR at approximately 25°C the radicals formed using the TiCl3H2O2 radical-generating method and the olefinic alcohol substrates 2-methyl-3-buten-2-ol, 3-methyl-3-buten-1-ol, and cis-2-butene-1,4-diol. Our EPR results are in agreement with known preferred radical conformations for structurally analogous radicals and further verify that substituent electronic and steric effects influence the apparent reactivity characteristics in aliphatic alcohol substrates as observed in the TiCl3H2O2 radical-generating system. |
