Silyls aluminum halides

The use of reactive metal electrodes are also effective for the silylation of various organic halides and simple arenes [75]. For instance, Dunogues et al. reported that electrolysis of aryl chlorides in the presence of excess Me3SiCl in a one-compartment cell equipped with a sacrificial aluminum anode in 80 20 THF/HMPA gave the corresponding aryltrimethylsilanes (Scheme 36).

Reaction of methanetellurol with lithium aluminum hydride in diethyl ether caused liberation of hydrogen and formation of lithium tetrakis[methyltelluro]aluminate. This compound was not isolated but reacted with silyl or germyl halides to give silyl or germyl methyl tellurium derivatives4. 

Lithium tetrakis[methyltelluro]aluminate, prepared from methanetellurol and lithium aluminum hydride, reacted with silyl, germyl, and stannyl halides at low temperatures to produce, for instance, methyl silyl tellurium derivatives1. 

With chloroacetyl chloride and aluminum chloride, addition of chloride gave the P-chloro-a-silyl enone in addition to the alkynic ketone. Addition of halide has also been observed in alkynations of 2-alkoxy-1 -trimethylsily lethynes. ... 

There are several alternative methods for the formation of acylsilanes these include the reaction of silyl cuprates with acid halides, palladium-assisted coupling of acyl halides with hexamethyldisilane, the reaction of thiopyridyl esters with tris(trimethylsilyl)aluminum in the presence of Cu salts, and the hydroboration of trimethylsilyl-substituted alkynes. While all of these procedures are complementary, the method involving the title corqtound provides an easy, inexpensive route to acylsilanes.
