Regioselective reactions of electrophilic iron dicarbonyl cations, [(η5-C5R5)(CO)2Fe]+ (R = H, CH3) with heterofunctional amine ligands
(Elsevier, 2012)
The reactions of the ether salts [(η5-C5R5)(CO)2Fe(E)]BF4, (R = H, E = Et2O; R = CH3, E = THF) with various ligands possessing two different coordination sites have been investigated. It was established that [(Cp(CO)2Fe(OEt2)]BF4 ...
(μ-Formato-κ2O: O′) bis [dicarbonyl (η5-cyclopentadienyl) iron (II)] tetrafluoridoborate
(International Union of Crystallography, 2011)
In the structure of the title compound [Fe(2)(C(5)H(5))(2)(CHO(2))(CO)(4)]BF(4), each Fe(II) atom is coordinated in a pseudo-octa-hedral three-legged piano-stool fashion. The cyclo-penta-dienyl ligand occupies three fac ...

Effects of Grafting Azacrown Ether on Thermal and Swelling Properties of Chitosan Films
(Multidisciplinary Digital Publishing Institute, 2017-11-17)
The thermal and swelling properties of a series of azacrown ether-crosslinked chitosans prepared with varying molar amounts of N, N-diallyl-7, 13-diaza-1, 7, 10, 16-tetraoxa-dibenzo-18-crown-6 (molar equivalents ranging ...
Robust Variance Estimation by Linearization Techniques for Poverty Indicators
(Southern Africa Mathematical Sciences Association, 2018)
The need for a reliable and equitable means of measuring population disparity and providing guidelines on implementation of policy decisions has necessitated the search for a precise estimating scheme for poverty indicators. ...

Non-response weighting adjustment approach in survey sampling
(JKUAT Press Ltd, 2006)
Non-response problem is an issue of great concern to all the researchers because it pervades almost all survey research. This ultimately creates potential for bias. The higher the non-response rate the greater the bias if ...
