“…The alkylation of the hydroxy group in ligand L1 and L2 was performed in dry tetrahydrofuran using 1,3‐propanesultone for the introduction of the alkyl‐sulfonate group (Scheme ). Initially, the phenoxide was generated using the deprotonating agent NaH, followed by ring‐opening of the cyclic sulfonate (1,3‐propanesultone) via nucleophilic attack from the phenoxide species which occurs with cleaving of the C=O , . The modification occurred in high yield (82 %) when these reagents were added in slight excess.…”

The synthesis and characterisation of two new watersoluble Rh I mononuclear 1,4-diazabutadiene (DAD s ) complexes of general formula: [Rh(DAD s -R)(COD)], where (DAD s = sulfonated-tagged-1,4-diazabutadiene, COD = cyclooctadiene; and R = H or C 10 H 8 ), are described. The rhodium(I) complexes were obtained via a complexation reaction of [Rh(COD)(MeCN) 2 ]BF 4 with the sulfonated α-diimine (DAD) ligands, which were previ-ouslyobtainedfromaSchiffbasecondensationreactionof4-aminophenol with either 1,2-ethanedione or acenapthenequinone.
