The variable reaction behaviour of base-free tris(trimethylsilyl)methyl Lithium with trihalogenides of earth-metals and iron

Base-free tris(trimethylsilyl)methyl Lithium, Tsi-Li, reacts with the earth-metal trihalogenides (MHal3 with M = Al, Ga, In and Hal = Cl, Br, I) primarily to give the metallates [TSi-MHal3]Li. Simultaneous to this simple metathesis a methylation also takes place, mainly with heavier halogenides of Ga and In with excess Tsi-Li, forming the mono and dimethyl compounds Tsi-M(Me)Hal (M = Ga, In; Hal = I), Tsi-MMe2 (M = Ga), and the bis(trisyl)derivative (Tsi)2InMe, respectively and the main by-product 1,3-disilacyclobutane. Representatives of each type of compound have been isolated by fractionating crystallizations or sublimations and characterized by spectroscopic methods (1H, 13C, 29Si NMR, IR, Raman) and X-ray elucidations. Reduction takes place, when FeCl3 reacts with Tsi-Li (1:3 ratio) in toluene at 55-60°C, yielding red-violet Fe(Tsi)2, 1,1,1-tris(trimethylsilyl)-2-phenyl ethane and low amounts of Tsi-Cl. Fe(Tsi)2 is monomeric, crystallizes in the monoclinic space group C2/c and consists of a linear C-Fe-C skeleton with d(Fe-C) of 204,5(4) pm. Wiley-VCH Verlag GmbH, 2001.
