| description | Our recent study on formal halide adducts of disilenes led to the investigation of the synthesis and properties of β-fluoro- and chlorodisilanides. The reaction of the functionalized neopentasilanes (Me<sub>3</sub>Si)<sub>3</sub>SiSiPh<sub>2</sub>NEt<sub>2</sub> and (Me<sub>3</sub>Si)<sub>3</sub>SiSiMe<sub>2</sub>OMe with KO<i><sup>t</sup></i>Bu in the presence of 18-crown-6 provided access to structurally related β-alkoxy- and amino-substituted disilanides. The obtained Et<sub>2</sub>NPh<sub>2</sub>Si(Me<sub>3</sub>Si)<sub>2</sub>SiK·18-crown-6 was converted to a magnesium silanide and further on to Et<sub>2</sub>NPh<sub>2</sub>Si(Me<sub>3</sub>Si)<sub>2</sub>Si-substituted ziroconocene and hafnocene chlorides. In addition, an example of a silanide containing both Et<sub>2</sub>NPh<sub>2</sub>Si and FPh<sub>2</sub>Si groups was prepared with moderate selectivity. Also, the analogous germanide Et<sub>2</sub>NPh<sub>2</sub>Si(Me<sub>3</sub>Si)<sub>2</sub>GeK·18-crown-6 could be obtained. |
