Silylacetylene, silyl enol ether

Callium enolate and ethynylgallium, generated, respectively, from silyl enol ether and silylacetylene by treatment with CaCls, underwent carbogallation, and a-ethenylated ketones were obtained after workup with an aqueous acid... [Pg.363]

An unexpected rearrangement was observed during studies directed towards the synthesis of bicyclic keto silanes by the thermal rearrangement of cycloalkanones bearing an co-silylacetylenic chain P to the carbonyl group. Thus, the bicyclic enol silyl ether 2 was formed in 60-65% yield when the ketone 1 was heated neat at 300°C for 2 hours. [Pg.147]
