Ai. Almansour et C. Eaborn, PREPARATION OF ((I)PRME(2)SI)(3)CH AND ITS USE AS A SOURCE OF THE BULKY LIGAND ((I)PRME(2)SI)(3)C, Journal of organometallic chemistry, 489(1-2), 1995, pp. 181-183
The compound ((i)PrMe(2)Si)(3)CH has been made, and shown to be metall
ated slowly by MeLi in refluxing THF to give the lithium reagent ((i)P
rMe(2)Si)(3)CLi. That the latter can be used to attach the bulky ligan
d ((i)PrMe(2)Si)(3)C to a metalloid or metal centre was demonstrated b
y treating it with Me(2)SiHCl to give a 77% yield of ((i)PrMe(2)Si)(3)
CSiMe(2)H, which with iodine gave the iodide ((i)PrMe(2)Si)(3)CSiMe(2)
I. Reactions of ((i)PrMe(2)Si)(3)CLi with Me(3)SiCl and SiCl4 likewise
gave ((i)PrMe(2)Si)(3)CSiMe(3) and((i)PrMe(2)Si)(3)CSiCl3 in ca. 33%
and 16% yields, respectively.
