Recommanded Product: 1-Bromo-2-pentyne. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. 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. Author is Thadkapally, Srinivas; Farshadfar, Kaveh; Drew, Melanie A.; Richardson, Christopher; Ariafard, Alireza; Pyne, Stephen G.; Hyland, Christopher J. T..

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.
