Organohydridosilanes containing Y,C,Y-chelating ligands: Reactivity and vapour pressure studies

The syntheses of organohydridosilanes containing Y,C,Y-chelating ligands of the general formula PhL1-3SiH2 (1, L1 = C6H3(CH2OtBu)2-2,6; 2, L2 = C6H3(CH2OtBu)-2-(CH2NMe2)-6; 3, L3 = C6H3(CH2NMe2)2-2,6) are reported. While PhL1SiH2 (1) is crystalline and molecular structure was determined by X-ray diffraction, the vapour pressures of oily compounds 2 and 3 were determined as well. In addition, the effect of the donor atoms upon the reactivity of organohydridosilanes 1-3 was studied further.
