The synthesis and application of (E)-1,2-disilylethene 5 as a central functional building block in a sequential Hiyama coupling/Narasaka acylation reaction are described. Its use in the rapid and versatile construction of α,β-unsaturated carbonyl motifs found in a number of polyunsaturated natural products has been demonstrated. It was observed that due to the differential intrinsic reactivity of the
