A selective method for the synthesis of 1,6-substituted glycolurils has been developed. The glycolurils have been used for the synthesis of methylene-bridged glycoluril dimers bearing hydrogen atoms… Expand
Diphenyldichlorophosphonium trichloride-chlorine solvate 1:1, [PPh2Cl2]+Cl(3)(-).Cl2: an ionic form of diphenyltrichlorophosphorane. Crystal structures of [PPh2Cl2]+Cl(3)(-).Cl2 and…
An ionic form of diphenyltrichlorophosphorane, namely, diphenyldichlorophosphonium trichloride isolated as a dichlorine solvate (1), was obtained by treating PPh(2)Cl(3) with excess chlorine. The… Expand
Rearrangement of fused tetracyclic heterocycles induced by alkyl halides and formation of a new type of ‘proton sponge’
Abstract Intramolecular criss-cross cycloaddition of 3-substituted symmetrical homoallenyl azines 2 by heating in xylene lead to interesting fused heterocyclic systems consisting of four… Expand
Base-induced dismutation of POCl3 and POBr3: synthesis and structure of ligand-stabilized dioxophosphonium cations.
The interaction between POCl(3) or POBr(3) and pyridine or DMAP has been reinvestigated to clarify the discrepancies between previously published results concerning the Lewis acidity of phosphoryl… Expand
Intramolecularly coordinated organotin(IV) sulphides and their reactivity to iodine
Abstract Organotin(IV) sulphides (LSnPhS)2 (3) and (LSnPh2)2S (4) containing O,C,O chelating ligand (L = 2,6-(t BuOCH2)2C6H3−) were prepared by the reaction of parent organotin chlorides LSnPhCl2 (1)… Expand
DONOR-ACCEPTOR COMPLEXES OF SULFUR TRIOXIDE WITH 1,4-DIOXANE AND THEIR CRYSTAL STRUCTURES
Crystal and molecular structure of adducts C4H8O2·SO3 and C4H8O2·2SO3 were determined by X-ray structure analysis and Raman spectroscopy. Both compounds crystallize from excess of 1,4-dioxane as… Expand
A new rearrangement of fused tetracyclic heterocycles in an acidic medium in the presence of NaBH3CN
Abstract In an acidic medium the criss-cross cycloadduct 2 with four fused five-membered rings rearranges to a heterocyclic compound 3 with a completely different structure consisting of two… Expand
The Reaction of Selenium Trioxide with Dialkyl Ethers
The donor-acceptor complexes Et2O·SeO3 and (Me2O)2·SeO3 can be obtained as primary products by the reactions of selenium trioxide with dimethyl ether (Me2O) and diethyl ether (Et2O). The crystal and… Expand
The synthesis and characterization of new aminoadamantane derivatives of hexachloro-cyclo-triphosphazene
Abstract The reactions of hexachloro-cyclo-triphosphazene P3N3Cl6 (1) with 1-aminoadamantane (amantadine, Ad-NH2) and 1-amino-3,5-dimethyladamantane (memantine, Mem) were studied. New geminally… Expand
