Four new dinaphthosulfide and dibenzosulfide aza podands were synthesized. The synthesis of these podands was performed under three different reaction conditions: 1) diester, K2CO3, methanol, and RT; 2) diester, ethanolamine, and microwave (MW); and 3) diacid dichloride, ethanolamine, Et3N, CH2Cl2, RT. Two kinds of diester (dinaphthosulfide and dibenzosulfide) were used for the preparation of dihydroxy podands. These dihydroxy podands were reacted with thionyl chloride to afford dichloro podands. The second route gave excellent yields of dihydroxy podands. Dichloro podands are more soluble than dihydroxy podands in conventional solvents such as methanol, chloroform, and acetonitrile.

A facile two-step preparation of o-aryloxyphenols is described in which the key step is the intramolecular trapping of an α-keto sulfonium salt prepared by Pummerer rearrangement of a symmetrical o-hydroxyaryl sulfoxide to give an orthoquinone mono(monoth
Synthesis and Inclusion Properties of Sulfur-Bridged Analogs of Acyclic Phenol-Formaldehyde Oligomers

A series of compounds in which a part or all of the methylene bridges of acyclic p-methyl- and p-t-butylphenol-formaldehyde tetramers were replaced by sulfur bridge(s) was synthesized.It was found that though the sulfur-bridged tetramers formed crystalline host-guest complexes with a variety of organic compounds, they were different from the parent tetramers regarding their inclusion behavior.The number and position of the sulfur bridge(s), as well as the p-substituent of phenol in the tetramers, had a great influence upon the inclusion property.The thermal stability of complexes of the sulfur-bridged tetramers (SSS-a,b) with benzene, as estimated from their thermal dissociation rates, are lower than those of the parent tetramers (CCC-a,b).
Rearrangements and decompositions of thiobisphenols

2,2′-, 2,4′- and 4,4′-Monothiobisphenol separately rearrange in phenol at 180° in the presence of sodium hydroxide to give similar mixtures containing only 2,2′-, 2,4′- and 4,4′-monothiobisphenol in the approximate ratio, 45:45:10. The rearrangements appear to be intermolecular and they are interpreted in terms of polar processes which lead initially to the formation of o- and p-monothiobenzoquinones. 2,2′-Dithiobisphenol, 4,4′-dithiobisphenol and 4,4′-trithiobisphenol under similar conditions are desulphurated with the evolution of hydrogen sulphide also to give mixtures containing only 2,2 - 2,4′- and 4,4′-monothiobisphenol whilst 3,3′-dithiobisphenol is stable in alkaline phenol even after long periods at 180°. Similar initial heterolyses to o- and p-monothiobenzoquinones are suggested as sources of the monothiobisphenols and displacements of sulphide- or hydrosulphide-ions from intermediate benzeneperthiolate ions by carbanions derived from phenol are suggested as sources of the hydrogen sulphide.
