Darstellung und Eigenschaften von und Reaktionen mit metallhaltigen Heterocyclen, LXIX1) Unabhängige Mechanismen der Cyclocotrimerisierung von Thiophosphinitomangan‐Komplexen mit Alkinen. – Ein einfacher Zugang zu fünfgliedrigen Heterocyclen

Abstract: In solution the dimeric thiophosphinitomanganese complexes ((OC),Mn(~-S-PR:)]2 [R1 = Me (l), Et (2), nPr (3)] are in equilibrium with the monomeric species (OC)4Mn(qZ-S-PR1 2) (4-6). For R1 = iPr (7) and Cy (8) the complexes (OC),Mn(q'-S"'PR;) are kinetically stabilized. In THF 4-8 react with different activated alkynes RZC = CRZ to form the S-isomeric five-membered heterocycles (OC),kn-S--PR:-CRZ= ?R2 ( l l a , b , ei). With additional alkynes R3C E CR4, 11 a, b.ei are transformed into the thiaphosphamanganab… Show more
