Abstract
AbstractThe synthesis of three partially deuterated hexadecanethiols has been achieved. Thiols CH3(CH2)7(CD2)8SH, CD3(CD2)7(CH2)8SH and CD3(CH2)15SH were targeted, as these compounds, after formation of self‐assembled monolayers on Au(1 1 1) or Au nanoparticles, can provide mechanistic information pertaining to reactive atom migrations within the assembly. The syntheses of each of these compounds called upon Grignard coupling chemistry, which was activated by Li2CuCl4. Applicable deuterium containing fragments were either commercially obtained or constructed from by way of an inexpensive and efficient ring opening, protection and dimerization of THF‐d8. Sulfur incorporation was by thiolacetate substitution or addition reactions. The protocols presented possess general applicability in a number of syntheses requiring block‐deuterated fattyalkyl sections. Copyright © 2008 John Wiley & Sons, Ltd.
