• General Description: 1-Heptene (also known as 1-n-Heptene, NSC 74130, or n-Hept-1-ene) is a linear alkene that serves as a product in the selective hydrogenation of 1-heptyne. Catalytic studies involving bimetallic AuPd/TiO₂ systems demonstrate that 1-heptene can be obtained with high yield (~93%) under mild reaction conditions, particularly when the catalyst is reduced at lower temperatures (e.g., 40 °C). The selectivity and efficiency of 1-heptene formation are influenced by factors such as metal-support interactions, catalyst preparation methods, and reduction temperatures. Additionally, 1-heptene can be produced via photocatalytic dehydrogenation of alkanes using rhodium complexes, though the abstract provided lacks specific details on this pathway. Its formation is also observed in Pd-catalyzed hydrogenation reactions, where support morphology and metal dispersion play key roles in optimizing selectivity.
