A novel regioselective rhodium(I)-catalyzed hydroarylation of unactivated alkenes with arylboronicacids is described. The catalytic system employs [Rh(COD)OH]2 and BINAP to effect the addition of various arylboronicacids to protected allylic amines. The regioselectivity was found to be highly dependent on the protecting group, favoring the linear addition product with up to 92% yield and >20:1 regioselectivity

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
