A facile method for the transition-metal-free diarylation of isocyanates with arynes in the presence of cesium fluoride has been developed, which affords functionalized diaryl amines in moderate to excellent yields. This reaction has good functional group tolerance and provides excellent regioselectivity by utilizing a methoxy-substituted aryne precursor.

The invention provides 1-(2-arylindenyl) dicyclohexylphosphine which takes a good catalytic effect in carbon-nitrogen coupling reaction of chlorinated or brominated aromatic hydrocarbons and diphenylamine and has the general formulas shown in the specification. According to the preparation method of 1-(2-arylindenyl) dicyclohexylphosphine, 2-aryl indene serving as a raw material reacts with n-butyllithium in the presence of high-purity nitrogen to obtain 1-(2-arylindenyl) dicyclohexylphosphine. 1-(2-arylindenyl) dicyclohexylphosphine and the preparation method and application thereof have the beneficial effects that A, B, C, D, E and F can exist in the air stably; a catalyst consisting of a compound D and palladium dibenzylacetone can catalyze reactions between various chlorinated aromatic hydrocarbons and diphenylamine and the highest yield is high up to 82%; the reactions between brominated aromatic hydrocarbons with high steric hindrance and diphenylamine can be catalyzed by the catalyst and the highest yield is high up to 85%; the reactions between chlorinated or brominated heterocyclic aromatic hydrocarbons and diphenylamine can be catalyzed by the catalyst and the highest yield is high up to 62%.
