Allene 1 reacts at −40 °C with the phenyldimethylsilylcopper reagent 6, with the opposite regioselectivity to that shown by the corresponding silylcuprate reagent 2, to give allylsilanes 7 and 10–15 rather than vinylsilanes.

Silylcupration of allene using phenyldimethylsilyl-copper followed by conjugated addition to α,β-unsaturated ketones affords oxoallylsilanes with different substitution patterns. When the former oxoallylsilanes are treated with a Lewis acid they undergo highly stereoselective allylsilane terminated cyclization leading to mono-, bi-, and tricyclic methylenecyclopentanols.

allylsilane-containing divinyl ketones and oxoallylsilanes, respectively. They undergo highly stereocontrolled silicon-assisted intramolecular cyclizations when treated with protic or Lewis acid leading to cyclopentane ring-formation.
