The lithiation of different functionalised chlorinated materials (1a-c), dichlorinated compounds (1d-f) and benzofused cyclic ethers (1g,h) with lithium powder in the presence of catalytic amounts of either linear (LPP) or crosslinked (CPP) polyphenylene, in THF at temperatures ranging between -78 and 20degreesC, leads to the expected organolithium intermediates (1a-h), which by reaction with electrophiles [(BuCHO)-C-t, PhCHO, Et2CO, (CH2)(5)CO, PhCOMe, Me3SiCl] gives, after hydrolysis with water, the expected products 2aa-hf.
