Calcium complexes supported by chiral 1,2-diamines have been shown to be efficient catalysts for the asymmetric hydroamination of amino-olefin substrates; the calcium complexes [Ca(NNR){N(SiMe3) 2}(THF)] (R = tBu, iPr, Ph, 4-C 6H4F) give enantioselectivities of up to 26% which marks a significant increase based upon literature precedence. The structure of [Ca(NNPh){N(SiMe3)2}(py)] has been computed with density functional methods.
