The linear product is formed as the major product when in situ generated titanium complexes with aminopyridinato ligands are used as catalysts for hydroaminoalkylation reactions of styrenes (see scheme). The reaction is not limited to the use of N‐methylanilines and for the first time can be performed with N‐alkylanilines bearing alkyl groups larger than methyl, or even with dialkylamines. The best

The scientific interest in catalytic hydroaminoalkylation reactions of alkenes has vastly increased over the past decade, but these reactions have struggled to become a viable option for general laboratory or industrial use because of reaction times of several days. The titanium-based catalytic system introduced in this work not only reduces the reaction time by several orders of magnitude, into the

Metal‐catalyzed hydroaminomethylations of styrenes, which take place by CH bond activation, can be achieved in the presence of the catalyst [Ind2TiMe2] (Ind=η5‐indenyl). Corresponding reactions of 1‐alkenes with N‐methylanilines performed at temperatures between 80 °C and 105 °C usually take place with regioselectivities of better than 99:1 in favor of the branched product.
