• N'-(2-Alkynylbenzylidene)hydrazide
• H-Pyrazolo[5,1-a]isoquinoline-1-carbaldehyde (Triphenylphosphine)rhodium(I) chloride
• Silver triflate
• 2-Vinyloxirane

A novel and efficient route to H-pyrazolo[5,1-a]isoquinoline-1-carbaldehydes via a tandem reaction of N'-(2-alkynylbenzylidene)hydrazide with 2-vinyloxirane is described. The reaction proceeds through a silver(I)-rhodium(I) cooperative catalysis.
