Resumo: | The syntheses of various complexes of Pt(II), Pt(0) and Pd(II) with 2-chloro-1,3,2-dioxaphospholane, 2-fluoro-1,3,2-dioxaphospholane, 2-chloro-4,5-benzo-1,3,2-dioxaphospholane, 2-fluoro-4,5-benzo-1,3,2-dioxaphospholane, 2-chloro-1,3,2-dioxaphosphorinane, 2-fluoro-1,3,2-dioxaphosphorinane are reported. 31P{¹H} NMR studies of these complexes reveals some aspects still unexplored in terms of the magnitude of the coupling constants ¹J(PtP), which brings light to the soft and hard acid-base concept. This work also shows the 31P{¹H} nmr spectroscopic differences between cis and trans isomers. |

This work also shows the 31P{¹H} nmr spectroscopic differences between cis and trans isomers. |
