The synthesis of bis‐enones from alkenyl bromides and α,ω‐bis‐Weinreb amides via a double Grignard reaction is reported. The work contains reliable protocols for the double addition and the efficient generation of the required substituted alkenyl Grignard reagents from alkenyl bromide precursors.

catalysts for a range of stereoselective transformations. Their synthesis, however, has remained a tremendous challenge, which has prevented a broad and systematic exploration for applications in synthesis and catalysis. A modular approach to such ansa‐metallocenes that enables a facile modification of the ring substitution and the ligand bridge, as well as the introduction of various core metals, is
