Implication

New copper complexes demonstrate potential for oxidative cleavage of alkenes and Henry coupling, indicating effective catalytic properties.

Key Points

This research aims to investigate the influence of noncoordinating substituents on copper(II) complexes and their catalytic potential.
Synthetized twelve new copper(II) complexes with varying noncoordinating substituents.
Characterized the structures using appropriate techniques.
Tested selected complexes as catalysts for oxidation and Henry coupling reactions.
Achieved oxidative cleavage of styrene to benzaldehyde with yields up to 85%.
Using ultrasound assistance, the conversion to syn- and anti-β-nitroethanol yielded up to 99%.
Remarkable diastereoselectivity was observed towards the anti-isomer.
