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.
