Tris(trimethylsilyl)methyl-lithium, LiC(SiMe3)3, reacts with trimethoxyborane to give the compound (Me3Si)3CB(OMe)2 (7) and the lithium-boron complex LiB(OMe)4 (8).The latter is converted on crystallisation from methanol into the solvate (11), which has been characterised by X-ray diffraction.The hydrolysis of (7) gives the dihydroxyborane (Me3Si)3CB(OH)2 (2), which may be converted into the dichloride (Me3Si)3CBCl2 (12), the difluoride (Me3Si)3CBF2 (14), the fluoride hydroxide (Me3Si)3CB(F)OH (15), the boranes(Me3Si)3CBR2 , and the hydride (3) (thf=tetrahydrofuran).An X-ray study shows that crystals of (2) consist of hydrogen-bonded dimers.Tris(dimethylphenylsilyl)methyl-lithium, LiC(SiMe2Ph)3, reacts with boron trifluoride-diethyl ether to give (PhMe2Si)3CBF2 (5), which may be hydrolysed to the dihydroxyborane (PhMe2Si)3CB(OH)2 (6).
