Conclusions

  1. 1.

    3-Lichioarynes, generated from t-butyl o,o′-dilithiophenyl sulfones, react by polar addition with lithium aryls, aromatic lithioamides, lithium alkylthiolates, and lithium n-butoxide, by selective addition of the nucleophiles at position 2. Carboxylation of the adducts gives a series of 2-substituted isophthalic acids.

  2. 2.

    The self-condensation of 3-lithioarynes also involves polar addition. We have identified an oligomerization product incorporating three 3-lithioaryne units.
