Various substituted benzo-mono-, bis-, and tris-1,2,3-trithioles were synthesized by reaction of the corresponding thiolates with sulfur dichloride. Benzo-bis(trithiolo)pentathiepin was isolated as a by-product. These trithioles form with cyanide dib

A model of the proposed macrocyclic polypyrrole has been synthesized and in discussed. Also proposed is an interesting form of polypyrrole borne from these studies with a fullerene-like structure. A possible synthetic method to it is discussed.

The magnetic properties of 1,3,5,6-tetraphenyl-verdazyl and related verdazyls were characterized by static magnetic susceptibility measurements (1.8K ≤ T ≤ 300K, H ≤ 55 kOe), ESR (10 GHz, solid and solution) and proton NMR (360 MHz, dilute solu

The 1H NMR spectra of verdazyls displaying magnetic interactions are examined. This is the first occasion on which the 1H NMR spectra have been reported for these particular materials and the synthesis of a number of new verdazyls is also reported. T

In the reaction of bis(trimethylsilyl)carbodiimide ( 1 ) with excess PF 2 Cl only the monosubstituted carbodiimide 2a was obtained. The carbodiimide structure is suggested by 15 N and 29 Si NMR spectra. Two equivalents of 2a were found to react with
