Abstract A new and green method for the synthesis of α,β-unsaturated arylsulfones had been achieved through the condensation of aromatic aldehydes, chloroacetonitrile, benzenesulfinic acidsodiumsalt in the presence of 1-butyl-3-methyl imidazolium hydroxide ([bmim]OH) in EtOH under reflux. The ionic liquid was recovered and recycled for subsequent reactions. The advantages of this protocol were non-toxic

Novel preparations comprising branched ligands for the HisB10 Zn2+ sites of the R-state insulin hexamer. The preparations have a prolonged action designed for flexible injection regimes.
This invention relates to NPH-insulin (crystalline preparations) that are prepared in the presence of certain high-affinity ligands for the HisB10 Zn
2+
-sites of the R-state insulin hexamer. Preparation of NPH-insulin in the presence of high-affinity ligand results in crystalline NPH-insulin suspensions that are absorbed more slowly from subcutis than regular NPH-insulin. Hence the resulting action profile is longer and the spike is less pronounced than observed with regular NPH-insulin
