Palladium-catalyzed annulation of o-iodobiphenyls with o-bromobenzyl alcohols: Synthesis of functionalized triphenylenes via C-C and C-H bond cleavages

Treatment of o-iodobiphenyls with o-bromobenzyl alcohols in the presence of cesium carbonate under palladium catalysis affords a series of highly substituted triphenylenes. The reaction involves two C-C bond formations and C-C and C-H bond cleavages. A combination of palladium and an electron-deficient phosphine ligand proves to be effective for both decarbonylative cross-coupling and intramolecular cyclization.

Copper-catalysed bromoalkynylation of arynes

Arynes were found to be inserted into a C(sp)-Br σ-bond of bromoalkynes in the presence of a copper catalyst, giving (alkynyl)bromoarenes in a straightforward manner.

Halogen-metal exchange in 1,2-dibromobenzene and the possible intermediacy of 1,2-dilithiobenzene

(Chemical Equation Presented) The one-step high-yield synthesis of 1,2-bis(trimethylsilyl)-benzene from 1,2-dibromobenzene using tert-butyllithium and trimethylsilyltriflate is reported. A mechanistic investigation shows that 1,2-dilithiobenzene is not an intermediate in this reaction; the coexistence of trimethylsilyltriflate and tert-butyllithium at very low temperatures allows a sequence of bromine-lithium exchange and subsequent derivatization reactions to operate.

THE SYNTHESIS AND REACTIONS OF ortho BROMOPHENYLLITHIUM

Experimental conditions have now been developed whereby o-bromophenyl-lithium(II) may be prepared in excellent yields and used as an organometallic intermediate for the synthesis of a variety of ortho bromo substituted phenyl compounds (o-BrC6H4X).The thermal stability, decomposition products and reactions of II were studied.Reactions between II and a variety of substrates, e.g., CO2, dimethylformamide, fluorinated esters, hexafluorobenzene, and organosilicon chlorides were examined.
