A novel and efficient Pd-catalyzed one-pot reaction of ethyldiazoacetate, isocyanides, and imines for the synthesis of acrylamidines was developed. The multicomponent reaction may have occurred through an unpredicted ring-opening process of the ketenimine–imine [2 + 2] intermediate to form the acrylamidine products.
