Aryl triflates undergo LDA-mediated rearrangement to generate o-hydroxyaryl trifluoromethylsulfones. In some cases, partitioning between rearrangement and aryne generation can be controlled.
Regiospecific metalation of oligobromobenzenes

, p. 5384 - 5387 (2007/10/03)
The metalation of selected oligobromobenzenes with lithium diisopropylamide (LDA) was investigated. 1,3-Dibromo-substituted benzenes were metalated without special precautions since the resultant 2,6-dibromophenyllithium intermediates are relatively stabl

Reaction of halophenyl triflates with LDA in diisopropylamine at -78°C affords isomeric mixtures of halo-N,N-diisopropylanilines, occasionally accompanied by variable amounts of m-bis(N,N-diisopropylamino)benzene and/or small amounts of N,N-diisopropylaniline. Use of ortho- or meta-halophenyl triflates gives largely the m-haloaniline, while the p-haloaniline predominates in reactions of the para- isomer. The magnitude of the directing effects varies with the halide (Cl>Br>I).

3-Aryl-3-indolylphthalides, 3-aryl-3-pyrrolylphthalides and 3-aryl-3-carbazolylphthalides prepared by interaction of the appropriate 2-(heteroaryl)carbonylbenzoic acid and the appropriate phenylamine, and 3,3-bis(indolyl)phthalides prepared by the interaction of the appropriate 2-(indolyl)carbonylbenzoic acid and the appropriate indole are useful as color formers in pressure-sensitive carbonless duplicating systems, thermal marking systems and hectographic copying systems.
