A concise method of producing nylon 11, 12, or 13 precursors from oleic acid or an ester of oleic acid is described. The method involves cross-metathesis reactions as the key C-C bond formation step. Subsequent steps are provided to convert the metathesis product to the corresponding nylon precursors. Also provided are the products of the method.
Remarkably enhanced stability of the self‐assembled hydrogen‐bonded heterocapsule 1⋅2 by the encapsulation of 1,4‐bis(1‐propynyl)benzene 3 a was found with Ka=1.14×109 M−1 in CDCl3 and Ka2=1.59×108 M−2 in CD3OD/CDCl3 (10 % v/v) at 298 K. The formation of 3 a@(1⋅2) was enthalpically driven (ΔH°<0 and ΔS°<0) and there was a unique inflection point in the correlation between ΔH° versus ΔS° as a function
