Sodium–Potassium Alloy for the Reduction of Monoalkyl Aluminum(III) Compounds

“…SCHEME 8. Compounds 4,6,7,8,11,13,15,and 16 133 (2) 133 (2) 153 (2) 203 (2) 150 ( The bromine and iodine derivatives (14 and 15) were prepared by reacting CycTrisAlMe )THF (11) with the corresponding elements (Scheme 9).…”

“…The tris(trimethylsilyl)methyl group (Tris ligand) is an example for a sterically demanding ligand showing stabilizing electronic properties (6). The cluster [TrisM] of gallium (7), indium (8), and thallium (9) was prepared by reacting Ga Br )dioxane, InBr, and CpTl with TrisLi, respectively.…”

Synthesis and desilylation of some bis(trimethylsilyl)alkenes and polymers bearing bis(silyl)alkenyl groups

“…Tris(trimethylsilyl)methyllithium, made in almost quantitative yield from the reaction between tris(trimethylsilyl)methane and methyllithium [11][12][13], reacts with some non-enolisable aldehydes such as 2-naphthaldehyde, 2-thiophenealdehyde, 5-methylfurfural, 3-pyridinaldehyde, p-chlorobenzaldehyde and 2,6-dichlorobenzaldehyde with the formation of a series of 1,1-bis(trimethylsilyl)-2-arylalkenes containing heteroaryl and chloro substituents in the aromatic ring. The Peterson reaction readily gives the appropriate vinylbis(silanes) ( Table 1).…”

Correlated Rotation of the Me3Si Groups in Tris(trimethylsilyl)methanes

“…Materials: Tris(trimethylsilyl)methane was commercially avaiable; tris(trimethylsilyl) compounds were prepared by a known procedure: [15] To a solution of tris(trimethylsilyl)methane (5 mmol in 10 mL of anhydrous THF) a solution of methyllithium (1.6 m in Et 2 O, 6 mmol) was added at room temperature. The mixture was heated to reflux for 5 h, during which it turned yellow, and then cooled to room temperature.…”
