title: Photochemical intermolecular silylacylations of electron-deficient internal alkynes.
abstract: Light-induced Brook rearrangements of acylsilanes facilitate silylacylation reactions of electron-deficient internal alkynes. A wide range of aromatic substituents on the acylsilane aryl group are tolerated, affording a series of functionalized enonyl silanes. The presence of electron-withdrawing substituents on the alkyne is crucial for the success of the addition process.
