Ring-opening reactions within porous metal-organic frameworks.
Two new metal-organic framework (MOF) structures, IRMOF-3b and -3c, were prepared by ring-opening reaction of 1,3-propanesultone and 2-methylaziridine with an amine functionalized MOF, IRMOF-3. The new structures are permanently functionalized with covalently linked sulfonate and alkyamine units, respectively. The underlying framework structure is retained after reaction as confirmed by powder ...
متن کاملReductive ring opening reactions of diphenyldihydrofullerenylpyrroles
The reductive ring opening reaction conditions for the simple [60]fullerenyldihydropyrrole 1 have been optimized to include acetic acid in the reaction mixture to rapidly protonate the anionic intermediate. Under these conditions, the ring opened dihydrofullerene 2 was obtained in 68% yield. Under slightly modified conditions and at −78 °C, the reductive bis-ring opening of the tethered trans-4...
متن کاملPreparation and ring-opening reactions of N-diphenylphosphinyl vinyl aziridines
Predominantly (E)-N-diphenylphosphinyl vinyl aziridines are prepared by a reaction of N-diphenylphosphinyl imines with α-bromoallyllithium in the presence of freshly fused ZnCl2. These aziridines undergo a ring-opening reaction with a variety of carbon and heteronucleophiles, in good yield, and generally with good regioselectivity.
متن کاملRing-opening reactions of 2-aryl-3,4-dihydropyrans with nucleophiles.
Ring-opening reactions of 2-aryl-3,4-dihydropyrans with nucleophiles were reported for the first time. A possible mechanism was also proposed. Finally, this method was used in the synthesis of a novel tetrahydrocarbazole derivative that possesses a biologically active skeleton.
متن کاملThe acid-mediated ring opening reactions of α-aryl-lactams.
4-Aryl-azetidin-2-ones (β-lactams) undergo ring opening with triflic acid to give cinnamamides which, in benzene, react further to give 3-aryl-3-phenyl-propionamides. Prolonged reaction times in benzene give 3,3-diphenyl-propionamide via an aryl/phenyl exchange. Lactams of ring size 7 and higher also ring open, but only 7- and 8-membered rings give pure diphenylalkylamides. AlCl(3) only ring op...
