An efficient and regioselective synthesis of polysubstituted benzene derivatives was achieved via multicomponent reaction of a substituted cyclopropenone acetal and two alkyne molecules. The synthesis utilizes cyclopentadienone acetal as an intermediate a

(Matrix presented) Highly selective cross [2 + 2 + 2] cycloaddition of two different monoynes is achieved by using a catalytic amount of [Ir(cod)Cl] 2 and ligand. The ligand had a considerable effect on the reaction. When 1,2-bis(diphenylphosph

Bis(dibenzylidene acetone)palladium reacts readily with N-aryl diazadienes (dad = ArN=CRCR=NAr) and two moles of dialkyl acetylenedicarboxylates ECCE (E = COOR) to form the palladacyclopentadienes (dad)PdCE=CECE=CE (2a-h).With a propiolic ester HCCE
