heteroarenes with unactivated alkenes by Au(III)-catalyzedintermolecularhydroarylationunder mild reaction conditions was developed. This method features a short reaction time (5 h) under mild conditions and has a broad substrate scope, including electron-rich arenes and heteroarenes, terminal and internal substituted aryl alkenes, and unactivated aliphatic alkenes.

Rhenium complexes have been shown to catalyze the alkylation of arenes with alkylhalides. When arenes were reacted with an alkyl chloride in the presence of a catalytic amount of rhenium complexes, such as bromopentacarbonylrhenium(I) [ReBr(CO)5], tricarbonylcyclopentadienylrhenium(I) [Re(C5H5)(CO)3] and decacarbonyldirhenium [Re2(CO)10], alkylation of the arenes proceeded under mild conditions to

Die Erfindung betrifft ein Verfahren zur Herstellung von hochmolekularem, gegebenenfalls verzweigten Polyarylensulfiden aus Alkalisulfiden, gegebenenfalls im Gemisch mit Alkalihydrogensulfiden und Dihalogenaromaten in einem polaren Lösungsmittel, in Gegenwart von 0,1 bis 6,0 Mol-%, bevorzugt 0,25 bis 4,0 Mol-% einer aromatischen Monoalkoxy- bzw. Monoalkylthioverbindung. Die so erhaltenen Polyarylensulfide haben reproduzierbar einstellbare Schmelzviskositäten bzw. Molmassen und zeichnen sich durch eine geringere Korrosion aus.
