“…The synthesis of 2-(hydroxyethylthio)-1,3-thiazole-4,5-dithiolene proligand 2 involves the reaction of 1 in the presence of an excess of 2-iodoethanol. This original transformation, first discovered with simple alkylating reagents such as MeI or EtI, 42 has been successfully extended here to 2-iodoethanol. When the reaction was performed in refluxing dichloromethane, as previously described with MeI and EtI, the proligand 2 was obtained in very low yield (7%) only.…”
