Economy Structure, Productivity And Economic Growth: Towards Methodological Perspective

As economic sectors’ performance targeted at country’s economic growth through the prism of inputs to production can not be implied without productivity phenomenon in the context of sustainable development, this paper is purposed to provide one aspect of the relevant methodologies for productivity phenomenon evaluation in the structure of economy. Scrutinized scientific literature proposes the following possible perceptions of productivity targets: as labor moves from low to high productivity a sector, in such a way contributing to aggregate country’s productivity growth, and as productivity increasement within sectors. Different variations of shift-share analysis methods have been provided to measure the impact of structural change on aggregate productivity growth

Synthesis of new heterometallic complexes by tin–sulfur bond cleavage of pySSnPh3 (pySH=pyridine-2-thiol) at triruthenium and triosmium centres

The ruthenium-tin complex, [Ru(2)(CO)(4)(SnPh(3))(2)(mu-pyS)(2)] (1), the main product of the oxidative-addition of pySSnPh(3) to Ru(3)(CO)(12) in refluxing benzene, is [Ru(CO)(2)(pyS)(SnPh(3))] synthon. It reacts with PPh(3) to give [Ru(CO)(2)(SnPh(3))(PPh(3))(kappa(2)-pyS)] (2) and further with Ru(3)(CO)(12) or [Os(3)(CO)(10)(NCMe)(2)] to afford the butterfly clusters [MRu(3)(CO)(12)(SnPh(3))(mu(3)-pyS)] (3, M=Ru; 4, M=Os). Direct addition of pySSnPh(3) to [Os(3)(CO)(10)(NCMe)(2)] at 70 degrees C gives [Os(3)(CO)(9)(SnPh(3))(mu(3)-pyS)] (5) as the only bimetallic compound, while with unsaturated [Os(3)(CO)(8){mu(3)-PPh(2)CH(2)P(Ph)C(6)H(4)}(mu-H)] the previously reported [Os(3)(CO)(8)(mu-pyS)(mu-H) (mu-dppm)] (6) and the new bimetallic cluster [Os(3)(CO)(7)(SnPh(3)){mu-Ph(2)PCH(2)P(Ph)C(6)H(4)}(mu-pyS)[(mu-H)] (7) are formed at 110 degrees C. Compounds 1, 2, 4, 5 and 7 have been characterized by X-ray diffraction studies. (C) 2010 Elsevier B.V. All rights reserved
