32005-36-0, Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 32005-36-0
A 1 – (2- […] ) b cyclohexyl phosphine and its preparation method and application (by machine translation)
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%.
