Efficient Catalytic Sonogashira Reaction Catalysed by Modified Fibre-Palladium(II) Complex in Air

Abstract

A hydroxylamine modified polypropylene fibre [Pd(II)-AOFs] was synthesised and used to catalyse the Sonogashira reaction between phenylacetylene and iodobenzene. The results showed that highly efficient catalytic activity can be achieved for the cross-coupling reaction. More importantly, the reaction conditions are moderate and do not require inert gas protection. The catalyst could be readily extracted by simple operations and conveniently recycled four times without an obviously significant decrease in activity.

An improved method for the synthesis of phenylacetic acid derivatives via carbonylation

“…As reported previously, nanoscale Pd colloids can be stabilized by quaternary ammonium salts, which prevent undesired agglomeration and promotes carbonylation. [15][16][17][18][19][20][21][22] In this work, Pd ions played the role of a Pd colloid. The activities of Co(CH 3 COO) 2 /PPh 3 (0.13 mmol) and CoCl 2 / PPh 3 (0.13 mmol) were evaluated for comparison.…”
