Abstract: Gas-phase tetrapositively charged M(HMNTA)24+ (M = Zr, Hf, Th, and U) ions were generated via electrospray ionization of the M(ClO4)4 and N,N,N',N',N″,N″-hexamethylnitrilotriacetamide (HMNTA) mixtures in acetonitrile. In these complexes, the Zr4+, Hf4+, Th4+, and U4+…

Abstract: The unique nucleophilic character of the carbonyl oxygen of 4-hydroxy coumarin has been observed by the BF3·OEt2 catalyzed reaction of 4-hydroxycoumarin and alkynes. The reactions of 4-hydroxycoumarin and substituted 4-hydroxycoumarin with various terminal alkynes have…
