Competitive Priorities and Competitive Advantage in Jordanian Manufacturing

The purpose of this research was to explore and predict the relationship between the competitive priorities (quality, cost, flexibility and delivery) and the competitive advantage of firms in the Jordanian Industrial Sector. A population of 88 Jordanian manufacturing firms, registered on the Amman Stock Exchange, was targeted using a cross-sectional survey employing a questionnaire method of data collection. The results of the data analysis indicate a significant relationship between competitive priorities and competitive advantage. The research suggests that recognising and nurturing this relationship provides the master key for a firm to survive in a turbulent environment. Therefore, operational and marketing strategies should place emphasis on competitive priorities such as quality, cost, flexibility and delivery to achieve, develop and maintain competitive advantage. This study is one of the first to examine the relationship between the competitive priorities of Jordanian manufacturing firms and their competitive advantage

Structural properties of azaphosphirane and its W(CO)5 complex. A density functional study

Properties and ring opening reactions are investigated for azaphosphirane and its P-phenyl and W(CO)5 complex using density functional theory (B3LYP). Azaphosphirane has a relatively small N-inversion barrier of 10.8 kcal mol−1 and a high 56.8 kcal mol−1 ‘turnstile’ P-inversion barrier. Its strain energy is 26.5 kcal mol−1at G3(MP2). The P---C bond is the weakest bond. Only 27.4 kcal mol−1 is needed to break it, which is half that needed for both the C---N and P---N bonds. This P---C ring opening to the P,N-ylide is endothermic by 8.5 kcal mol−1. P-phenyl substitution has little effect neither on the geometries nor on the energy of the ring opening. Complexation by W(CO)5 leads to a tighter ring but the energy for breaking the P---C bond still requires 27.8 kcal mol−1. The resulting P,N-ylide is only 3.9 kcal mol−1 less stable than azaphosphirane. Cleaving either the C---N or P---N bond remain much more demanding processes. The calculations suggest that the reactivity of azaphosphirane may well have its origin in the readily accessible P,N-ylide. Its influence on the reaction of phosphinidenes with imines is discussed

Synthesis, Structures and Strain Energies of Dispirophosphiranes. Comparisons with Dispirocyclopropanes

Six novel dispirophosphirane complexes have been synthesized from the reaction of bicycloalkylidenes with the electrophilic phosphinidene complex PhPW(CO

Asymmetric permanganate-promoted oxidative cyclization of 1,5-dienes by using chiral phase-transfer catalysis

Neither synthesis nor detection in matrix isolation experiments has been accomplished for the parent compounds of phosphanylalanes and -gallanes of type A. H2 elimination reactions between [(CO)5WPH3] and H3ENMe3 (E=Al, Ga) have enabled the first synthesis of Lewis acid/base stabilized complexes of the type B. Comprehensive density functional theory (DFT) calculations on the aluminum systems verify the high stability of the complexes of type B
