4-ETHYNYLANILINE Chemical Properties,Uses,Production
Reaction
4-Ethynylaniline, also known as p-ethynylaniline, is a terminal alkyne. Its synthesis using 2-methyl-3-butyn-2-ol (MEBYNOL) has been reported. The transition metal catalyzed polymerization of 4-ethynylaniline to afford poly(4-ethynylaniline) has been reported.[3]The impact of the surface functionalization with 4-ethynylaniline on the thermal behavior of multi-walled carbon nanotubes (MWNTs) and graphene has been investigated.
Uses
4-Ethynylaniline may be used in the synthesis of N-methyliminodiethyl 4-(4-ethynylphenyliminomethyl) benzeneboronate. It can also be used to prepare an acetylene ligand, HC2-NDI (NDI= 1,4,5,8-naphthalenediimide).It can be used as an alkyne component in a synthesis of indoles from nitroarenes in the presence of a palladium-phenantroline catalyst.
