• For the synthesis of iodoalkenes by radical addition of perfluoroalkyl iodides, see: J. Org. Chem., 47, 2251 (1982).
• 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). For coupling with vinyl halides catalyzed by Tetrakis(triphenylphosphine)palladium(0), 10548 in the presence of CuI as an example of a route to enynes, see: Tetrahedron Lett., 30, 6997 (1989); Org. Synth. Coll., 9, 117 (1998). CuCl-TMEDA catalyzed oxidative (Hay) coupling gives bis(TMS)-1,3-butadiyne: Org. Synth. Coll., 8, 63 (1993).
• 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):
