Abstract

The invention provides a ferrocenyl-containing arylamine compound and a synthesis method thereof. A trifluoromethanesulfonic acid-2-(trimethylsilyl) phenyl ester compound is used as a benzyne precursor, cesium fluoride is used as an alkali, 18-crown-6-ether is used as a phase transfer catalyst, and a ferrocenyl arylamine structural unit is efficiently constructed through a one-pot reaction under the condition of no additional metal catalyst. The reaction overcomes the defects that a transition metal or noble metal catalyst needs to be added in the conventional reaction, the requirements on a substrate and reaction conditions are harsh and the like, the reaction is simple in substrate synthesis, reagents are easy to obtain, target molecules are obtained simply and quickly with high atom economy, and a brand-new way is provided for developing the ferrocenyl-containing arylamine compound.

Description

technical field [0001] The invention belongs to the field of organic compounds, and in particular relates to a ferrocenyl-containing arylamine compound and a synthesis method thereof. Background technique [0002] Amines and their derivatives are important chemical intermediate products with a long production history, large output and wide application. Aromatic amines and their derivatives are widely used in chemical industry, medicine, agrochemicals, photographic chemicals, additives, surfactants and polymer production, and are important organic raw materials. N atoms on arylamine compounds have strong electron-donating ability and good electronpositivity, so these compounds generally have high hole injection and migration abilities. As important organic synthesis intermediates, arylamine compounds can be used in the preparation and application of organic dyes, nonlinear optical materials, liquid crystal materials, optical information storage materials and optical switch m...
