“…For instance, aliphatic terminal olefins such as 1-octene, 1-dodecene, 1-tetradecene, 1-hexadecene, and 1-octadecene are hydroaminomethylated with morpholine by using a [{RhCl(cod)} 2 ] catalyst to form mixtures of the corresponding linear and branched amines. [44] On the other hand, in the presence of phosphane ligands, for example, xantphos derivatives, highly regioselective and efficient hydroaminomethylations are achieved. [45] Good n:iso ratios (up to 10:1) have been observed for the hydroaminomethylation of the functionalized olefin 3,3-dimethylpent-4-ene-2-one with secondary amines by using phosphane-free rhodium catalysts.…”
