A stereospecificallylic amination of unactivated secondary (secondary)-allylic alcohols is reported. The primary (primary)-allylic amine can be isolated directly or protected in situ. Spectroscopic studies have shed light on the structure of the catalytically activeIr x (P,olefin)2I complex.

Enantioselective vinylation of aldehydes via direct catalytic asymmetric Grignard reaction of aldehdyes and the vinyl Grinard reagent is a long‐standing challenge. This work demonstrated that the magnesium (S)‐3,3′‐dimethyl BINOLate enantioselectivelycatalyze the direct vinylation of aldehydes with the deactivated vinylmagnesium bromide by bis(2‐[N,N′‐dimethylamino]ethyl) ether (BDMAEE) in the addition
