One-pot synthesis of fluorescent 2,5-dihydro-1,2,3-triazine derivatives from a cascade rearrangement sequence in the reactions of 1,2,3-triazolium-1-aminide 1,3-dipoles with propiolate esters
Butler, Richard N.; Fahy, Aoife M.; Fox, Anthony; Stephens, John C.; McArdle, P.; Cunningham, D.; Ryder, Alan G. (American Chemical Society (ACS), 2006-07-01)The reactions of 1,2,3-triazolium-1-aminides 1 ( readily available from benzil bishydrazones) with propiolate esters leads to fluorescent 2,5-dihydro-1,2,3-triazine derivatives 2, 3 in one pot. These synthetic reactions ... -
Theoretical characterization of pentazole anion with metal counter ions. calculated and experimental 15n shifts of aryldiazonium, -azide and -pentazole systems†
Burke, Luke A.; Butler, Richard N.; Stephens, John C. (Royal Society of Chemistry (RSC), 2001-01-01)Theoretical studies of proposed structures for NaN5, KN5, Mg(N-5)(2), Ca(N-5)(2), and Zn(N-5)(2) metal complexed pentazole anions have been carried out with the RHF, MP2, MCSCF, and DFT theoretical methods. Additional DFT ...
