    Tsuji-Trost Cyclization of Disulfonamides: Synthesis of 12-Membered, 11-Membered, and Pyridine-Fused Macrocyclic Triamines 

    Ali, Rameez; Anugu, Sreenivasa R.; Chawla, Reena; Demillo, Violeta G.; Goulinet-Mateo, Florian; Gyawali, Sagar; Hamal, Sunil; Jones, Dylan E.; Lamprecht, Katrin; Le, Truc D. T.; Lumangtad, Liezel A.; Pflug, Nicholas C.; Sama, Alekhya; Scarbrough, Emily D.; Bell, Thomas W. (ACS Omega, 2019)
    Macrocyclic triamine disulfonamides can be synthesized by double Tsuji-Trost N-allylation reaction of open-chain disulfonamides with 2-alkylidene-1,3-propanediyl bis(carbonates). The previously used Atkins-Richman ...

    Unusual nitro-coordination of Eu(III) and Tb(III) with pyridinyl ligands 

    de Bettencourt-Dias, Ana; Bauer, Sebastian; Viswanathan, Subha; Maull, Brandi C.; Ako, Ayuk M. (2012)
    A new ligand family based on picoline, bipyridine and terpyridine containing a nitro moiety has been synthesized and its coordination and sensitization ability for lanthanide ions has been studied. Three new complexes were ...

    ZnS nanoparticles sensitize luminescence of capping-ligand bound lanthanide ions 

    Tigaa, R.A.; Lucas, G.J.; de Bettencourt-Dias, Ana (2017)
    2,6-Bis(diethylamide)-4-oxo(3-thiopropane)pyridine (BDP) and 2,6-bis(methyl ester)-4-oxo(3-thiopropane)pyridine (BMP) were synthesized. These compounds chelated LnIII ions and sensitized their emission. The 3:1 complexes ...
