Arylation of azoles was performed via C–H functionalization with 1-aryltriazenes in the presence of PdCl2, dppe, CuCl and ButOLi.

Reaction of aryltrimethylammonium iodides with arylzinc chlorides in the absence of a transition-metal catalyst to form biaryl compounds was performed under mild conditions. The reaction was suitable for a broad scope of substrates and exhibited good compatibility of functional groups. The Mg ion was demonstrated to markedly promote the reaction.
