nanotubes (CNTs) provide a certain potential activation of catalysis in heterogeneous catalytic organicreactions. Herein, an efficient Ag/CNT‐catalyzed synthesis of enamines via hydroamination of activatedalkynes with aromatic amines has been described. This catalyst still retains catalytic activity after being recycled and reused three times. In addition, it represents a green and environmentally

pyrimidine derivatives are presented herein: 1) A catalyst-free multicomponent reaction of electron-deficient alkynes, aliphatic amines and formaldehyde and 2) Ag(I)-catalyzedsynthesis of pyrimidines from electron-deficient alkynes, anilines and formaldehyde by a dominoreaction. Under optimized conditions, the multicomponent reactions were accomplished with high regioselectivity and excellent yields. A computational
