Abstract
Official abstract text for this publication.
The invention provides an organosilane compound having a more bulky substituent group than the existing organosilane compounds. The compound is represented by formula (1) wherein R 1 is a C 4 -C 10 tertiary hydrocarbon group, R 2 is a C 1 -C 10 alkyl group, and LG is halogen or trifluoromethanesulfonyloxy.
First claim
Opening claim text (preview).
The invention claimed is: 1. An organosilane compound having a bulky substituent group, represented by the general formula (1): wherein R 1 is a C 4 -C 10 tertiary hydrocarbon group, R 2 is a C 1 -C 10 straight alkyl group, and LG is halogen or trifluoromethanesulfonyloxy. 2. The organosilane compound of claim 1 wherein LG is halogen. 3. The organosilane compound of claim 1 wherein LG is trifluoromethanesulfonyloxy. 4. A method for preparing the organosilane compound of claim 2 , comprising the step of reacting a hydrogensilane compound having the general formula (2): wherein R 1 and R 2 are as defined above, with a halogenating agent. 5. A method for preparing the organosilane compound of claim 3 , comprising the step of reacting a hydrogensilane compound having the general formula (2): wherein R 1 and R 2 are as defined above, with trifluoromethanesulfonic acid.
