triphenylphosphine; lithium chloride; bis(dibenzylideneacetone)-palladium(0) in tetrahydrofuran a soln. of ferrocene in THF was added to a suspn. of biphenyl, PPh3 and LiCl in THF, the mixt. was heated to reflux for 48 h, cooled to room temp. (Ar); diluted with CH2Cl2, washed with 10percent aq. HCl, water, with brine, dried over MgSO4, the solvent was removed in vac., chromd. on silica gel (isohexane; isohexane-CH2Cl2);
