complexes for Suzuki-Miyaura and Buchwald-Hartwig cross-coupling reactions involving heteroaromatic halides at roomtemperature is reported. The first examples of roomtemperatureSuzuki-Miyaura cross-coupling of deactivated aryl chlorides with alkenyl boronic acids are also disclosed. Terminal substitution at the allyl moiety of the palladium complex facilitates its activation at roomtemperature leading

Ammoniak. Die Substitution von 3 gelingt durch Einwirkung von Alkylhalogeniden auf sein Natriumsalz oder durch reduktive Alkylierung mit aromatischen und aliphatischen Ketonen. Acetophenon‐Mannichbasen werden durch 3 umaminiert. Mit Methyl‐vinyl‐keton und Acrylnitril bildet 3 keine Additionsprodukte. Addition an Phenylglycidsäurederivate führt zur Bildung entsprechender Derivate des β‐Phenyl‐isoserins
3,4-Dehydroquinoline was easily generated from 3-bromoquinoline and a complex base NaNH2-tBuONa. Nucleophilic condensation of amines and thiolates were performed in good yields. (C) 2001 Elsevier Science Ltd. All rights reserved.
