Cyclisation by Tributyltin hydride ( Bu3SnH) || TBTH/AIBN || Part 1|| cyclisation reactions • Tributyltin hydride is an organotin compound with the formula (C4H9)3SnH. Organotin hydrides are very good radical reducing agents due to the relatively weak, non-ionic bond between tin and hydrogen (Bu3SnH 74 kcal/mol) that can cleave homolytically. • Sn-H is weaker bond than C-H bond. Hence it requires an Initiator molecule • AIBN(Azobisisobutyronitrile)[(CH3)4C2(CN)2]N2 • Intramolecular cyclisation is radical based Ring formation reactions • Ring formation is preferentially 5 membered ring • Vinyl radicals are less stable or more reactive than Alkyl Radicals • organic chemistry • ,Bu3SnH, • TBTH, • AIBN, • Cyclisation by Tributyltin hydride • ,tributyltin hydride, • intramolecular cyclization, • intermolecular cyclization reaction, • organotin compound, • Azobisisobutyronitrile, • Initiator molecule, • ring formation, • 5 membered heterocyclic compounds, • Tributyltin hydride reaction mechanism • ,Bu3SnH AIBN reaction, • Bu3SnH mechanism, • Bu3SnH reaction, • Tributyl tin hydride CSIR NET, • Tributyl tin hydride mechanism, • Tributyl tin hydride, • tributyltin, • dayachemistry • #tributyltin • #AIBN • #cyclization • #Bu3SnH
