Infrared Spectra of Bisarylsulfonimide Derivatives

概要

論文の詳細を見る
The infrared (IR) spectra of bisbenzenesulfonimide, bistoluenesulfonimide and benzenetoluenesulfonimide are reported together with the spectra of the corresponding N-deuterated samples. The isotopic shifts of the bands near 3180 cm^<-1> and 1400cm^<-1> of bisarylsulfonimide derivatives give the evidence of the assignment of these bands to the N-H group. The dichroic properties of these bands in bisbenzenesulfonimide suggest that the molecule has the C_2 symmetry. On this ground, the symmetric and antisymmetric S-N-S stretching bands are clearly distinguished from each other in the polarized spectra. The IR spectrum of bispentadeuterobenzenesulfonimide has been measured. The effects of the N-deuteration and the ring deuteration on the characteristic frequencies are discussed. The IR spectra of the corresponding N-alkyl-bisarylsulfonimide derivatives are also discussed.
