Azide promotion of alkane oxidations catalyzed by metal complexes in solution

Autor: Paul E. Ellis, Shahid N. Shaikh, James E. Lyons

Publikováno v: Inorganica Chimica Acta. 270:162-168

The oxidation of light alkanes catalyzed by metal complexes in solution is promoted by Group 1 metal azides. Yields of oxygenated reaction products are greatly enhanced when catalytic amounts of azides are added to the reaction mixture. The addition

Synthesis and structural characterization of an oxotechnetium(V) N,N′-ethylenebis( 2-phenoxyacetamido) complex

Autor: Shahid N. Shaikh, Michael J. Abrams, Jon Zubieta

Publikováno v: Inorganica Chimica Acta. 186:87-90

The reaction of [(n-C 4 H 9 ) 4 N][TcOCl 4 ] with N,N ′-ethylenebis(2-phenoxyacetamide), H 4 epa, in methylene chloride, yields orange crystals of [(n-C 4 H 9 ) 4 N][TcO(epa)]. The X-ray structure reveals an oxotechnetium(V) core with the oxo group
