Abstract
In the reactions between tertiary acetylenic alcohols and trans-[PtClH(PPh3)2] no insertion reactions into the Pt-H bond occur. In the presence of primary alcohols, R″OH, monochlorobis(triphenylphosphine)platinum complexes of alkynyl ethers, [PtCl{C≡CCR(R′)(OR″)}(PPh3)2], are obtained. Secondary and tertiary alcohols promote an intramolecular dehydration reaction and complexes of alkenylalkynes are formed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
