Name: 1-Bromo-2-pentyne. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about Synthesis and characterization of nano-zinc wire using a self designed unit galvanic cell in aqueous medium and its reactivity in propargylation of aldehydes. Author is Mondal, Bibhas; Mandal, Siba Prasad; Kundu, Mousumi; Adhikari, Utpal; Roy, Ujjal Kanti.
Electrochem. was used for propargylation of carbonyls in aqueous ZnCl2 medium. For electrochem. process the authors designed a unit galvanic cell. ZnCl2 was used as stoichiometric reagent and causes electrochem. deposition of Zn in cathode. Wire shaped nano Zn architecture was formed in cathode during electrochem. process which is the active reagent. Homopropergylic alcs. were synthesized in good yields. After the organic reaction is over aqueous solution containing Zn salts can be reused up to 5th cycle without significant loss of reactivity.
