Photo-allylation of various aromatic carbonyl compounds with a penta-coordinated allylsiliconate reagent was remarkably accelerated by the addition of a donor molecule. As the oxidation potential of the allylsiliconate was significantly decreased in the presence of a donor molecule, the more efficient photo-induced electron transfer from the allylsiliconate to the excited substrate was enabled by the hexa-coordination of the silicon atom.
