A methodology for the construction of sterically congested quaternary centers via the trapping of vinyl carbocations with silylketeneacetals is disclosed. This main group-catalyzed α-vinylation reaction is advantageous as methods to access these congested motifs are limited. Moreover, β,γ-unsaturated carbonyl moieties and tetrasubstituted alkenes are present in various bioactive natural products
