Unexpected formation of a sterically protected nitrogen pentasulfide ArNS5 (Ar = 2,6-dimesityl-4-methylphenyl) and the X-ray crystallographic analysis
Abstract
A stable cyclic nitrogen pentasulfide ArNS5 (Ar = 2,6-dimesityl-4-methylphenyl) was unexpectedly obtained by passing the corresponding N-thiosulfinylaniline through a silica gel column and the chair form of the six-membered ring was revealed by X-ray crystallographic analysis.
