An analysis of the palladium-catalyzed activation of carbon–carbonsingle bonds within triarylmethanols has led to a greater understanding of factors influencing the β-aryl elimination process responsible for C–C bond cleavage. A series of competition reactions were utilized to determine that β-aryl elimination of aryl substituents containing ortho-substitution proceeds with significant preference
