Formula: C5H7Br. 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 Metal-Free Hydroamination of Alkynes: A Mild and Concise Synthesis of Thiazolo[3,2-a]indoles and their Cytotoxic Activity. Author is Short, Spencer; Rhodes, Steven; Bhave, Vishakha S.; Hojo, Ryoga; Jha, Mukund.
A metal-free, mild and efficient method for the synthesis of thiazolo[3,2-a]indoles I (R1 = H, Me, Et, Ph, 4-methoxyphenyl, 4-nitrophenyl; R2 = H, CH3; R3 = H, 6-Cl, 7-F, 7-CH3) has been developed starting from indoline-2-thiones II (R4 = H, 6-Cl, 5-Me, 5-F). The reaction methodol. involves first the formation of thermally labile 2-(prop-2-ynylthio)-1H-indole intermediates II, which undergo base-mediated intramol. hydroamination to produce the title compounds I in excellent yields.
