Reactions of polyhalonitrosoarenes with phenylacetylene

Abstract

Phenylacetylene reacts with polyhalonitrosoarenes to give two isomers of 1 phenyl 1,2 bis(2,4,6 trihalophenylnitrono)ethane.

Domino Reaction between Nitrosoarenes and Ynenones for Catalyst-Free Preparation of Indanone-Fused Tetrahydroisoxazoles

“…For example, terminal alkynes reacted with nitrosoarenes to afford indole derivatives via 1,4 diradical intermediates . When a bulky 2,6-dihalonitrosoarene is used, an α-styryl cation is produced, which is attacked by another nitrosoarene to provide a dinitrone (Scheme a) . Beside terminal alkynes, the Liu group found that ynamide and propiolate could also react with nitrosoarene to give 2-oxoiminylamide and α-imidoyl nitrone with gold salt as the catalyst (Scheme b–c). , As for the common internal alkyne, fewer examples have been reported due to its relatively lower reactivity compared with the terminal alkyne, ynamide and propiolate.…”
