Description

(1) Technical field

[0001] The present invention relates to [2.2] p-cyclophane derivatives, in particular to 1-bis(phenyl)phosphino-2-bis(pentafluorophenyl)boryl-[2.2] p-cyclophane and 1-bis(2,4 ,6-trimethylphenyl)phosphino-2-bis(pentafluorophenyl)boryl-[2.2]p-cyclophane and its preparation method, and its catalytic hydrogenation reduction reaction in imine compounds as non-metallic catalyst in the application. (2) Background technology

[0002] Lewis acid-base theory is one of the most important basic theories in classical chemistry. It expands the concept and scope of acids and bases, enables people to better understand acid-base reactions, and is used to explain numerous reaction mechanisms. When a Lewis acid and a base meet, the Lewis base provides a lone pair of electrons, and the Lewis acid provides an empty orbital, and the two are combined through a coordination bond to form a stable Lewis acid-base adduct, such as Et 2 O·BF 3 , H 3 N·BH 3 Wait. There is also a...
