Synthesis and reactivity of a new type of crown ether thiosemicarbazone

Abstract

: Palladacycle compounds containing a crown-ether moiety in their structure have been scarcely studied in the past years, although they offer the possibility of combining the crown-ether application as sensors with the catalytic behavior of palladacycles. Maybe the reason for this is because they present a strong interaction with silica making the purification of the new products a difficult task. Nevertheless, in this communication we present the synthesis and characterization of a new palladacycle bearing a 15-crown-5-ether.
