Tris(biphenyl-4-yl)silyl-endcapped polyynes
Chalifoux, Wesley A.,Ferguson, Michael J.,Tykwinski, Rik R.
, p. 1001 - 1006 (2008/03/12)
The use of tris(biphenyl-4-yl)silyl (TBPS) as a large protecting group for polyynes has been investigated. The basic building block, TBPS-C≡C-TMS (1), is synthesized in a new "one-pot" reaction through the sequential addition of lithiated nucleophiles to
