	STUDIA CHEMIA - Issue no. 1 / 2013

	Article:	A THEORETICAL APPROACH ON THE STRUCTURE AND REACTIVITY OF MODEL PHOSPHASTANNAPROPENES. Authors: PETRONELA M. PETRAR, GABRIELA NEMEŞ, LUMINIŢA SILAGHI-DUMITRESCU.


	Abstract: The stability of phosphastannapropenes and their coordination ability towards transition metal centers was estimated by DFT calculations. The influence of several substituents on the stabilization of the model compounds MesP(MLn)=CCl-SnClRR’, MesP(η² -MLn)=CCl-SnClRR’ (R = H, R’; R’ = H, Me, Mes, Ph, Fl, Mes; MLn = W(CO)₆ , PdCl₂ Me, PtCl₂ Me has been studied. Keywords*: phosphastannapropenes; palladium-, tungsten- and platinum complexes; low coordinate phosphorus compounds; multiple bonding; DFT.
