Tin(II) chloride, which is insensitive to water and air, mediated the coupling reaction between alkynes and aldehydes as a Lewis acid in nitromethane to produce (E)-α,β-unsaturated ketones by a skeletal transformation in which one alkynic carbon a...

Seven-membered metallacyclic allene compounds, 1-zirconacyclohepta-2,3,6-trienes, were synthesized by intermolecular coupling between alkynes and 1-en-3-ynes on a zirconium atom. X-ray diffraction studies and NMR spectroscopic observation indicate...

The cyclotrimerization of terminal alkynes, such as ethyl propynoate, arylacetylenes, and alkylacetylenes, catalyzed by phosphine-free [IrCl(cod)]2 is induced by a catalytic amount of tin(II) chloride in 1,4-dioxane to afford 1,2,4- and/or 1,3,5-t...
