Rh2(ii)-catalyzed cyclization/gem-hydrosilylation of benzene-fused 1,6-enynones

Dirhodium( ii )-catalyzed cyclization/geminal hydrosilylation of 1,6-enynes that accommodates primary, secondary and tertiary silanes is reported. This protocol enables one-step synthesis of bicyclo[3.1.0]hexanone silanes and naphthol-derived silanes.
