Mass spectra of heterocyclic compounds VI. 3,4-dihydro-1H-2,3-benzothiazine 2,2-dioxides
摘要:
AbstractThe mass fragmentation behaviour of 3,4‐dihydro‐1H‐2,3‐benzothiazine 2,2‐dioxides was studied. The rationalizations suggested are supported by accurate mass measurements, metastable evidence and deuterium labelling.
An object of the present invention is to provide a curable composition made mainly of an organic polymer having a reactive silicon group, exhibits a good curability without using any organic tin compound substantially, and gives a cured product having a sufficient strength; and to provide a catalyst composition. The object is solved by a curable composition, comprising a polymer (A) having a silicon-containing group which can be crosslinked by forming a siloxane bond, and a fluoride salt compound (B).
