“…Also, when hexachlorodisilane is treated with o-tolyllithium, only two halogens per silicon atom are replaced by o-tolyl groups (74). This is to be contrasted with the reported facile preparation of tri-o-tolylmethyl from chloro(tri-o-tolyl)methane and mercury (193). Evidently the steric factors in these cases are great enough to prevent Wurtz-type coupling, so the failure of the reaction R3SiCl + Na -» R3Si* + NaCl to occur must be due to some other factor.…”

“…Evidently the steric factors in these cases are great enough to prevent Wurtz-type coupling, so the failure of the reaction R3SiCl + Na -» R3Si* + NaCl to occur must be due to some other factor. It is suggested (193) that this second factor is probably a decreased resonance stabilization of the triarylsilyl radical as compared with its carbon analog.…”

“…This carbinol was also prepared by the previously published method. 19 Tri-F-chlorophenylcarbinol.-4,4'-Dichlorobenzophenone (12 g.) was added to 0.073 mole of F-chlorophenylmagnesium bromide in 150 cc. of ether.…”
