of arylacetic acid with aryl halides in the presence of a palladium(0) catalyst proceeds with a Grignardreagent (2 equiv.) to afford diarylated acetic acids. Deprotonation was confirmed by treatment with allyl bromide, which revealed that the use of EtMgCl or tBuMgCl at room temperature to 60 °C resulted in complete deprotonation. After deprotonation of (4-methoxyphenyl)acetic acid under such conditions
