Abstract
Abstract A photoredox/copper‐catalyzed 1,4‐difunctionalization of 1,3‐enynes with readily available trifluoromethylaminating reagent and TMSCN was developed. This reaction proceeded at mild conditions, affording the corresponding trifluoromethylaminated allenes in good yields and excellent regioselectivity. The synthetic application of the resulting products has also been demonstrated by the transformation to N −CF 3 oxazolidinones.
