The complex [(dppe)Pt{μ-SCH(CH 2 CH 2 ) 2 NMe} 2 PtIMe 3 ] has been synthesised and structurally characterised by X-ray diffraction. It consists of dinuclear sulfur-bridged enantiomeric pairs containing a folded Pt II (μ-S) 2 Pt IV ring with the thiolate substituents in anti configuration. 1D and 2D variable temperature ...
In the reactions of nitrone 1 with several methylene-γ-butyrolactones 2-5 we have isolated and identified in all the cases the corresponding [3+2] cycloadducts. In all the adducts the oxygen atom of the dipole has linked to the more substituted carbon atom of the exocyclic double bond of the lactone. For lactone 5 the exocyclic double bond has shown higher reactivity than the endocyclic. Herein...
