phosphine-free Suzuki-Miyaura carbon-carbon cross-coupling reactions of activated and deactivated aryl halides and 2-acetyl-5-bromobenzofuran with various aryl- or heteroarylboronic acids were investigated. A benzothiazole-based palladium(II) complex was used as a precatalyst for the reactions under both thermal and microwave conditions in air using water as a solvent. palladium - catalysis - microwave irradiation

spectroscopy, nuclear magnetic resonance, and conductance measurements), and explored for its catalytic activity in Suzuki–Miyaura and Heck–Mizoroki cross-coupling reactions of different aryl- and heteroaryl halides with arylboronic acids and styrene, respectively, using the microwaveirradiation conditions. The electronic arrangement, type of hybridization, and nature of bonding in the Pd-complex were investigated
