ChemInform Abstract: SYNTHESIS AND SOME CHEMICAL REACTIONS OF NAPHTHYL‐CONTAINING SECONDARY‐TERTIARY ACETYLENIC Γ‐GLYCOLS

Abstract

Das 3‐Octin‐diol (I) wird durch Triäthylsilan (II) infolge einer zuerst stattfindenden Meyer‐Schuster‐Umlagerung in die Carbonylverbindung (III) übergeführt, während das 3‐Hexindiol (IV) mit (II) sowohl zu einer Carbonylverbindung (V) wie auch, infolge normaler Addition an die Dreifachbindung, zu (VI) reagiert.

Advances in Transition‐Metal‐Catalyzed Hydrogermylation of Alkenes and Alkynes†

“…Similar to the hydrogermylation of alkenes, catalysts that are used for the hydrosilylation reactions are also tested for the hydrogermylation of alkynes. [ 118‐129 ] Corriu and Moreau reported the hydrogermylation reaction of phenylacetylene with HGePh 3 catalyzed by H 2 PtCl 6 •6H 2 O, (PPh 3 ) 2 PtCl 2 , and (PPh 3 ) 3 RhCl. These catalytic reactions give β ‐( E )‐isomers as the main products, accompanied by α‐ isomers and β ‐( Z )‐isomers (Table 10).…”
