- METHOD FOR PRODUCING ORGANOSILICON COMPOUND, METHOD FOR PRODUCING AMINO ARYL GROUP-CONTAINING ORGANOSILICON COMPOUND AND ORGANOSILICON COMPOUND
-
PROBLEM TO BE SOLVED: To provide a production method that can efficiently produce an amino aryl group-containing organosilicon compound at low cost. SOLUTION: An organosilicon compound represented by general formula (1) is produced by the following reaction or the like, and a benzyl group is deprotected from an amino group thereof, so that an amino aryl group-containing silicon compound is produced. R1-R4, R7 each represent a hydrogen atom, an alkyl group or an alkoxy group; R 5 and R6 each represent an alkyl group; X is a halogen atom; M is a lithium atom or magnesium halide; n is an integer of 1-4; m is an integer of 1-n.

- Diamino compounds and their production method
-
The present invention is to provide diamino compounds useful to polyamide raw materials for production of liquid crystal alignment layers having excellent voltage holding ratios without development of image-sticking phenomena, a method for producing the compounds and liquid crystal display devices equipping the liquid crystal alignment layers. The Diamino compounds are represented by the general formula (1): STR1 wherein R indicates hydrogen or an alkyl group having 1 to 8 carbon atoms, further, X, Y and Z indicate hydrogen, an alkyl group having 1 to 3 carbon atoms or fluorine, respectively, and a part or all of them may be the same or different, and the positions of these substitutive groups may be ortho positions or meta positions.
