An ether-free, internally coordinated dialkylcalcium(II) complex
journal contribution
posted on 2023-06-08, 07:26 authored by Martyn P Coles, Sebnem E. Sozerli, J David Smith, Peter B Hitchcock, Iain DayThe alkylpotassium compound KC{SiMe3}(2){SiMe(2)hpp} (hppH = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine) reacts with a slurry of CaI2 in toluene to give the internally coordinated dialkylcalcium(II) complex Ca(C{SiMe3}(2){SiMe(2)hpp})(2). The molecular structure in the solid state shows short Ca-N and long Ca-C bonds and a wide C-Ca-C angle. The H-1 and C-13 NMR spectra suggest that the metallacycle is transiently opened in toluene at room temperature.
