Abstract
Cu (II) salen complex immobilized on graphene oxide nanosheets [Cu (II)
salen@GO] was synthesized with 3‐chloropropyltrimethoxysilan as a linker
and wholly characterized using various techniques like X‐ray diffraction,
Fourier‐transform infrared, scanning electron microscopy/energy‐dispersive
X‐ray spectroscopy, transmission electron microscopy, as well as atomic
absorption spectroscopy (AAS). Cu (II) salen@GO as an effective heterogeneous
catalyst has been investigated for the Sonogashira coupling reaction in
dimethylsulfoxide with good to high yield (98%) in 4 hr at 110°C when the
loading of Cu was 0.7 mmol g−1 based on Cu element analysis by AAS. It
was understood that heterogeneous catalyst was as active as its homogeneous
analog, and presented good recoverability and no significant loss in activity
within successive runs.
