REGIO- AND STEREO-CHEMISTRY OF THE COUPLING REACTION OF PHENYLSULPHENYL-, PHENYLSULPHINYL- AND PHENYLSULPHONYL-PENTADIENYL METALS

The coupling reaction of phenylsulphenyl-, phenylsulphinyl and phenylsulphonyl-pentadienyl metals 3a-g has been studied showing that while 3c-g couple in any case regioselectively and stereoselectively, the coupling of 3a-b is countercation and electrophile dependent.The α-regioisomeric coupling products of phenylsulphenylpentadienyl metals may undergo sigmatropic rearrangement, those of phenylsulphinyl- and phenylsulphonyl-pentadienyl metals give fast double sigmatropic isomerization.

REAKTIONEN ORGANOELEMENTSUBSTITUIERTER PENTADIENE: KOMPLEXIERUNG MIT UEBERGANGSMETALLEN SOWIE PRAEPARATIVE ANWENDUNG DER LITHIIERUNGSPRODUKTE (1)

The pentadienyllithium compounds 3, 5, 9, 12, and 15 react with ketones exclusively in α-position of the organoelement group to give the alcohols 4, 6, and 10 or the triene 13 (R = Ph), respectively.By reaction of organoelement substituted pentadienes with Na2PdCl4, Fe2(CO)9, Fe3(CO)12, and NiCl2 five well defined transition metal complexes (16-20) and three palladium clusters of unexplored structure have been obtained.From 1-(phenylthio)-2,4-pentadiene 2-(methoxy)-1-(thiophenyl)-4-pentene (23) was synthesized via palladium complex 22.
