Novel p-xylylene-bis(thioacetic) acid (p-XBTA) and its co-crystals with 2-amino-4,6-dimethylpyrimidine (DMP) have been synthesized and characterized by single-crystal X-ray diffraction, infrared spectroscopy and thermal analysis methods (TG/DSC). Depending on the crystallization conditions, three different multicomponent crystal forms have been isolated with various chemical compositions and stoichiometries of the co-formers. The ATR-FTIR spectra of the co-crystals display the stretching vibration bands for the co-formers with associated shifts confirming the formation of new phases. DSC and TG were used to reveal the relative stabilities of new solids compared to those of the co-formers.

A novel class of bis selena and/or thiadiazoles were prepared by the reaction of semicarbazones of 3,6-dithiaoctahydrophenanthrene-1,8-dione, 3,6-dithiaoctahydroanthracene-1,8-dione and 3,7-dithiaoctahydroanthracene-1,5-dione with SeO2 and SOCl2, respectively. The latter, in turn, were obtained from 1,2-, 1,3-and 1,4-xylylenedimercaptoacetic acids.

Phase transfer catalysis has been found to be effective for the preparation of symmetrical bis-sulfides (4) in high yields by a one-pot procedure which consists of generating the thiolate ions from S-alkylisothiouronium salts (2) and then reacting with alkyl halides (3).
