- Brominating agent for Li enolates of esters, by displacement of bromomalonate, giving better results than bromine itself where unsaturation is present: Rec. Trav. Chim., 96, 72 (1977).
- A so-called 'forcing Knoevenagel' methodology has been employed with ketones in the presence of tributylantimony to give the alkylidenemalonates: Tetrahedron, 51, 8033 (1995). Under similar conditions, Michael acceptors were found to undergo cyclopropanation of the olefinic double bond: Tetrahedron, 45, 3011 (1989).
