Stepwise synthesis of a stable diphosphasilirane and its unexpected dimerization.
نویسندگان
چکیده
The synthesis of the thermally stable bicyclic diphosphasilirane O(SiiPr2P)2SiiPr2 (4) was achieved via oxidation of the alkaline earth metal substituted cyclic diphosphanide 3 with 1,2-dibromoethane. Nonetheless, during extended storage at low temperature, impurity induced rearrangement in favour of the dimeric species [O(SiiPr2P)2SiiPr2]2 (5) is observed.

Zirconium catalyzed alkyne dimerization for selective Z-enyne synthesis.
The regioselective head-to-head dimerization of alkynes is catalyzed by a dibenzyl tethered bis(ureate) zirconium precatalyst with aniline as an additive. This system also gives outstanding stereoselectivity to furnish Z-enynes in high yields. A dinuclear reactive intermediate has been characterized, which provides a potential mechanistic rationale for the unexpected regio- and stereoselectivit...
متن کاملThermodynamic Characterization of the Aggregation Phenomena of SafranineT by Spectral Titration and Chemometric Analysis
The dimerization constants of Safranine T have been determined by studying the dependence of its absorption spectra on the temperature in the range 30–70 ◦C at different total concentrations of Safranine T (1.03×10−5, 1.44×10−5 and 1.73×10−5 M). The monomer–dimer equilibrium of Safranine T has been determined by applying MCR-ALS method on the absorpti...
متن کاملUnexpected one pot pseudo four-component reaction for the synthesis of (10E)-N-benzylidene-2-phenylH-imidazo [1,2-a]pyridin-3-amine derivatives under solvent-free conditions
This work described an efficient Pseudo four-component synthesis of (10E)-N-benzylidene-2-phenylH-imidazo[1,2-a]pyridin-3-amine derivatives from 2-aminopyridin, malononitrile and arylaldehydes in the presence of NaOH under solvent-free and conventional heating condition in good to excellent yields. A wide range of aromatic aldehydes would easily undergo condensations with 2-aminopyridin and mal...

متن کاملSmI2-mediated dimerization of indolylbutenones and synthesis of the myxobacterial natural product indiacen B
The synthesis and reactivity of indole derivatives substituted in the benzene section was studied. Starting materials 4- and 6-iodoindole were conveniently prepared via the Batcho-Leimgruber route and purified by sublimation. Novel vicinally indolyl-substituted cyclopentanols with unexpected cis-configuration were formed by SmI2-mediated reductive dimerization of a 4-(indol-6-yl)butenone, obtai...
