Catalyzed hydrofunctionalizations of unsaturated substrates are of tremendous interest, primarily because of their atom efficiency.[1] Intramolecular catalytic cyclohydroamination of aminoalkenes can be efficiently promoted by d0 complexes of the heavy alkaline-earth (Ae) metals,[2, 3] typically Ca and in rare cases Sr, as recently exemplified by the groups of Hill,[4] Ward,[5] and Roesky.[6] The catalytic activity of these complexes, which are based ...
