  • Pd catalyzed coupling with aryl bromides or iodides gives aryl TMS alkynes, from which the TMS group is readily cleaved by K2CO3 in MeOH: Synthesis, 627 (1980); J. Org. Chem., 46, 2280 (1981). Coupling with 1-bromo-2-nitrobenzene or ethyl 2-bromocarbanilate gives indole precursors. Other terminal alkynes lead to 2-substituted indoles: Heterocycles, 24, 31 (1986):
  • Cross-coupling with aryl halides can also be catalyzed by Pd-C in the presence of Ph3P, CuI and Et3N: Synth. Commun., 20, 2059 (1990); for an example, see 2-Bromonaphthalene, A15300. Pd catalyzed coupling with quinolinol and isoquinolinol triflates has also been reported: Tetrahedron, 51, 3737 (1995).
