Abstract

An organosilicon compound represented by general formula (1). The present invention is able to provide an organosilicon compound which has excellent adhesion during processing and high bonding strength, while exhibiting antirust corrosion resistance at high levels, and which is useful as a metal surface treatment agent.

(In the formula, R represents a hydrolyzable group; R′ represents an alkyl group; A represents an alkylene group; R 1 and R 2 , R 2 and R 3 , or R 3 and R 4 among the R 1 , R 2 , R 3 and R 4 moieties may combine together to form an aliphatic or aromatic ring skeleton, and in cases where a ring skeleton is not formed, each one of the R 1 , R 2 , R 3 and R 4 moieties independently represents a hydrogen atom or an alkyl group; and m represents a number of 1-3.)

First claim

The invention claimed is:

1. A method for producing an organosilicon compound having the general formula (1):

wherein R is a hydrolyzable group, R′ is a C 1 -C 4 alkyl group, A is a C 1 -C 8 alkylene group, R 1 , R 2 , R 3 and R 4 are each independently hydrogen or a C 1 -C 6 alkyl group when they do not form a ring structure, or a pair of R 1 and R 2 , R 2 and R 3 , or R 3 and R 4 may bond together to form an aliphatic or aromatic ring structure, and m is an integer of 1 to 3, comprising the step of reacting an organosilicon compound having the general formula (3):

wherein R, R′, A and m are as defined above, with a benzotriazole compound having the general formula (4):

wherein R 1 , R 2 , R 3 and R 4 are as defined above.

2. The method of producing an organosilicon compound of claim 1 , having the general formula (2):

wherein R 5 is a C 1 -C 10 alkyl or C 6 -C 10 aryl group, R 1 , R 2 , R 3 , R 4 and m are as defined above, and Me is methyl.
