Deprotonation of aryl methanedithioate 5 bearing a bowl-type bulky subsituent with lithium tetramethylpiperidide at low temperature gave organolithium species 9 which was in equilibrium with a dimeric species 10; 9 extruded C=S at higher temperatures, thu
Synthesis of highly reactive organosulfur compounds

, p. 414 - 418 (2007/10/03)
Application of novel bowl-type and dendrimer-type steric protection groups to the first synthesis of stable aromatic S-nitrosothiols is described. These compounds showed remarkable thermal stability whereas they easily reacted with appropriate reagents. X-ray crystallographic analysis established their structures, where the C-S-N-O linkage adopts only the syn conformation. Synthesis of a stable sulfenic acid by taking advantage of the bowl-type substituent is also delineated.

The first stable aromatic S-nitrosothiol, S-nitroso-4-t-butyl-2,6-bis[(2,2",6,6"-tetramethyl-m-terphenyl-2'-yl)methyl]benzenethiol, was synthesized by the nitrosation of the corresponding thiol and the structure was established by X-ray crystallography. Its oxidation and reactions with some nucleophiles were carried out.
Syntheses and structures of stable sulfenyl iodides bearing novel bowl-type and dendrimer-type substituents
Goto, Kei,Holler, Michel,Yamamoto, Gaku,Okazaki, Renji
, p. 313 - 314 (2007/10/03)
Arenesulfenyl iodides with unprecedented stability were synthesized by iodine oxidation of the corresponding arenethiols bearing bowl-type and dendrimer-type substituents. X-ray crystallographic analysis established their monomeric structures.
Synthesis and crystal structure of an arenesulfenyl iodide with unprecedented stability
Goto, Kei,Holler, Michel,Okazaki, Renji
, p. 1915 - 1916 (2007/10/03)
An arenesulfenyl iodide with unprecedented stability was synthesized by oxidation of a thiol bearing a novel bowl-type substituent with iodine, whose monomeric structure was determined by X-ray crystallographic analysis.
Synthesis and structure of a novel molecular bowl with an all-carbon and acyclic framework
Goto, Kei,Holler, Michel,Okazaki, Renji
, p. 3141 - 3144 (2007/10/03)
A novel all-carbon molecular bowl 2 where the central functionality is surrounded by two rigid tetramethyl-m-terphenyl units was designed. Bromide 3 was readily synthesized by copper(I)-catalyzed coupling reaction between 4 and 5. X-ray crystallographic analysis established that 3 has a bowl-shaped structure although it is an acyclic molecule. Butyl sulfide 6 and thiol 8 were synthesized via lithiation of 3.
