Abstract:

The reaction of KB[sec-Bu](3)H with calcium iodide [LCa(mu-I).thf](2)] (1) and strontium iodide [LSr(mu-I).thf](2) (2) yields calcium trisec-butylborohydride LCaB(sec-Bu)(3)H.thf (3) and strontium trisec-butylborohydride LSrB(sec-Bu)(3)H.thf (4) (L = CH(CMe2,6-iPr(2)C(6)H(3)N)(2)), respectively. Compounds 2, 3, and 4 were characterized by multinuclear NMR spectroscopy, mass spectrometry, elemental analysis, and single crystal X-ray analysis, whereas 1 was characterized without X-ray structural analysis. Compounds 3 and 4 are monomeric in the solid state with a hydride ligation between the metal and boron centers.
