An efficient copper-mediated method for the oxidative alkynylation of diaryl imines with terminalalkynes is reported. This reaction provides the first catalytic and general synthesis of ynimines and allows for an easy preparation of these useful building blocks. An improved copper-catalyzedoxidative dimerization of imines to azines and the synthesis of dienes and azadienes from ynimines are also
