Put it on a ring: A rhodium(III) complex can catalyze the oxidative coupling of azomethine imines with olefins, leading to the synthesis of 1,2‐dihydrophthalazines, olefinated aldehydes, or fused pyridines, depending on the conditions used.

The rhodium(III)‐catalyzed coupling of azomethine ylides with alkynes via CH activation has been developed for the synthesis of indenamines in moderate to high yields. The coupled products can be further oxidized to indenones and derivatives.
