Size matters: For the first time since catalytic hydroaminoalkylation chemistry started 37 years ago, dimethylamine can efficiently be added to alkenes using an inexpensive and easilyobtainable Ti catalyst. The size of the flask determines whether the reaction gives monohydroaminoalkylation or dihydroaminoalkylation.

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

bisphenoxyiminato complexes based on highlysubstituted p- and m-terphenyl backbones were synthesized, and the corresponding atropisomers were isolated. In the presence of a phosphine scavenger, Ni(COD)2, the phosphine-ligated syn-dinickel complexes copolymerized α-olefins and ethylene in the presence of amines to afford 0.2-1.3% α-olefin incorporation and copolymerized amino olefins and ethylene with a similar
