Unusual reactivity of aryl aldehydes with triethyl phosphite and zinc bromide: A facile preparation of epoxides, benzisoxazoles, and α-hydroxy phosphonate esters
Abstract A facile preparation of trans-epoxides was achieved by a (EtO)3P-ZnBr2-mediated deoxygenation reaction of the corresponding 2-nitrobenzaldehydes. The sterically hindered analogues of 2-nitrobenzaldehyde underwent a reaction

Nickel-catalyzed decarbonylative polymerization of 5-alkynylphthalimides: A new methodology for the preparation of polyheterocycles
A nickel-catalyzed decarbonylative cycloaddition was developed, in which 5-alkynylphthalimides reacted to afford a new type of polyisoquinolone. It was demonstrated for the first time that decarbonylative cycloaddition can be an elementary process of polycondensation for the preparation of heterocyclic polymers.
