195Pt NMR--theory and application

This critical review highlights the progress in (195)Pt NMR over the last 25 years. In particular, some of the recent applications of (195)Pt NMR in catalytic and mechanistic studies, intermetallics and drug binding studies are discussed. (195)Pt NMR chemical shifts obtained from both theoretical studies and experiments are presented for Pt(0), Pt(II), Pt(III) and Pt(IV) complexes. (195)Pt coupling with various nuclei (viz. coupling constants) have also been collected in addition to data on (195)Pt relaxation. The latest developments in the theoretical knowledge and experimental advances have made (195)Pt NMR into a rich source of information in many fields. (164 references.).     

Regioselective Synthesis of Allyl Trimethylsilanes from Allylic Halides

Treatment of an allylic halide 1 with a trimethylsilyl metal reagent affords either trans allyl trimethylsilane 4 or the regioisomeric allyl trimethylsilane 3 with proper choice of reaction conditions.
