Abstract

" A'cause the Jut and dm are large compared to the J m and Jxx is much greater than JAA, the proton spectrum of the methylenes display a deceptively simple triplet with an apparent coupling constant of JAx= 9.0-10.0 Hz. The spectrum of ((trifluoroethy1) imino) sulfur difluoride is further simplified to a sextet because the methyl and sulfur fluorines have the same coupling constant with the protons. The generation of acetonitrile N-sulfide and ...
