Liquid sulfur as a reagent: synthesis of polysulfanes with 20 or more sulfur atoms with characterization by UPLC-(Ag~+)-coordination ion spray-MS

摘要

Diallyl disulfide reacts within minutes with liquid sulfur at 120°C giving a family of diallyl polysulfanes, All2S_n (n = 3-22), characterized by ultra-performance liquid chromatography-(Ag~+)-coordination ion spray-mass spectrometry (UPLC-(Ag~+)CIS-MS). Similarly, garlic oil (GO), bis-(2-methyl-2-propenyl), bis-(2-chloro-2-propenyl), bis-(3-methyl-2-butenyl), and bis-(2-cyclohexen-1-yl) disulfides all give families of polysulfanes with up to 22 sequential sulfur atoms. New members of families of silver chelators with up to 10 sulfur atoms were found in GO using UPLC-(Ag~+)CIS-MS.
