New metal-organic frameworks (MOFs) based on zinc and cadmium ions, terephthalic acid, and flexible ligands 1,5-bis(imidazol-1-yl)pentane or 1,6-bis(imidazol-1-yl)hexane were prepared and characterized by X-ray diffraction, thermorgavimetric analysis and IR spectroscopy. The imidazolyl ligands were prepared by a new robust procedure involving the reaction between imidazole and 1,5-dibromopentane or 1,6-dibromohexane in a superbasic medium (KOH in DMSO). MOFs based on 1,5-bis(imidazol-1-yl)pentane had diamond topology (dia) and are triply interpenetrated. Ligands with longer spacer 1,6-bis(imidazol-1-yl)hexane, terephthalate ions and zinc(II) ions formed five-fold interpenetrated metal-organic framework also with dia topology, while cadmium(II) ions with the same ligands formed eight-connected uninodal net with a very rare self-penetrated topological type ilc and a point symbol 4 24 .5.6 3 . The influence of the chemical composition of MOFs on their photoluminescent properties is investigated and discussed in detail.

We have formulated and developed a route for the synthesis of sulfur-containing heterocycles based on the interaction of sulfenyl chlorides with unsaturated compounds which occurs by ring closure at the nucleophilic center of the sulfenyl unit [1-6].In the current work reactions of 3,3-dimethyl-1-butene (1) with the hetarenesulfenyl chlorides 2a-d which contain a potentially nucleophilic nitrogen atom in the hetaryl unit: 4,6-dimethylpyrimidine-2-(2a), 3-cyano-4,6-dimethylpyridine-2-(2b), quinoline-8-(2c), and 1,3-benzothiazole-2-sulfenyl chloride (2d).

Ring closure reactions O 0130 Sulfenyl Halides in the Synthesis of Heterocycles. Part 2. Cyclization in Reactions of Hetarenesulfenyl Chlorides with 3,3-Dimethyl-1-butene. -Reaction of 3,3-dimethylbutene with hetarenesulfenyl chlorides (I) provides the β-chlorosulfides (III), which suffer intramolecular cyclization on storage in solution or, more rapidly, in MeNO2 containing LiClO4. -(BORISOV, A.
