| English abstract | 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 |
| Portuguese abstract | A síntese de vários complexos de Pt(II), Pt(0) e Pd(II) com 2-cloro-1,3,2-dioxafosfolana, 2-fluoro-1,3,2-dioxafosfolana, 2-cloro-4,5-benzo-1,3,2-dioxafosfolana, 2-fluoro-4,5-benzo-1,3,2-dioxafosfolana, 2-cloro-1,3,2-dioxafosforinana e 2-fluoro-1,3,2-dioxafosforinana é descrita. Estudos de RMN de 31P{¹H} destes complexos revelam alguns aspectos inexplorados em relação às constantes de acoplamento ¹J(PtP), os quais chamam a atenção para o conceito de ácidos e bases duros e macios. Este trabalho mostra também as diferenças espectroscópicas de RMN de 31P{¹H} entre isômeros cis e trans |
