✦ Synopsis

The reaction of ethoxyxcarbonyl isothiocyanate with water isothiocyanate. Compound 2 can be isolated chromatographically, but it is slowly oxidized when allowed to stand in in the absence of a solvent has yielded the new compound [EtO 2 CN=CS 2 C{N(H)CO 2 Et}{S 2 CN(H)CO 2 Et}] (1) in 76% the open air to form the thiuram disulfide 3. Compounds 1 and 3 were characterized crystallographically. Compound 1 yield that has been isolated in a crystalline form that contains one equivalent of ethoxyxcarbonyl isothiocyanate.

contains an imino-substituted dithietane ring with a dithiocarbamate substitutent bonded to one of the ring Compound 1 can be viewed as an adduct of a dimer of EtO 2 CN=C=S and the dithiocarbamic acid 2. Compound 1 carbon atoms. Compound 3 is a thiuram disulfide which has C 2 crystallographic symmetry. dissociates in solution to yield 2 and free ethoxyxcarbonyl

## Abstract An attempt to synthesize the Tenidap isomer **13** was performed starting from 2‐ethoxy‐5‐chloroindole (**9**). The acylation and carbamoylation reactions of **9** led to the expected intermediate **12**, however the hydrolysis of **12** in acidic or alkaline media did not yielded the e

The steady-state and time-resolved fluorescence and 1 H NMR spectra of a stilbenesulphonic acid salt, commonly used as an optical brightening agent, was studied as a function of concentration in aqueous solution. The aggregates, formed at higher concentrations, were shown to be predominantly dimers
