The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about Rhodium-catalysed tetradehydro-Diels-Alder reactions of enediynes via a rhodium-stabilized cyclic allene, the main research direction is isobenzofuran preparation; isoindoline preparation; indane preparation; enediyne Diels Alder reaction rhodium catalyst.Quality Control of 1-Bromo-2-pentyne.
Herein, tethered unconjugated enediynes R1CCCH=CHCH(R3)XCH2CCR2 [R1 = Ph, n-pentyl, 4-fluorophenyl, etc.; R2 = H, Et, Ph; R3 = H, Me, n-Pr; X = O, NTs, NNs, C(C(O)OMe)2] have been shown to undergo a facile room-temperature RhI-catalyzed intramol. tetradehydro-Diels-Alder reaction to produce highly substituted isobenzofurans, isoindolines and indane I. Furthermore, exptl. and computational studies suggest a novel mechanism involving an unprecedented and complex RhI/RhIII/RhI/RhIII redox cycle involving the formation of an unusual strained 7-membered rhodacyclic allene intermediate and a RhIII-stabilized 6-membered ring allene complex.
