Patent ID: 7109311

Claim:
A sulfonyldiazomethane compound having the following general formula (1): wherein R is each independently a substituted or unsubstituted straight, branched or cyclic alkyl group of 1 to 4 carbon atoms, G is SO 2 or CO, R 3 is a substituted or unsubstituted straight, branched or cyclic alkyl group of 1 to 10 carbon atoms or a substituted or unsubstituted aryl group of 6 to 14 carbon atoms, p is 1 or 2, q is 0 or 1, satisfying p+q=2, m is an integer of 3 to 11, and k is an integer of 0 to 4, with the proviso that in the event k is at least 1, at least one of R associated with k may bond with the R at the 4-position to form a cyclic structure with the carbon atoms on the benzene ring to which these R's are attached, and then, these two R's bond together to form an alkylene group of 3 to 4 carbon atoms.
