Procedure: 2-Methanesulfonyloxyundecane was prepared as described for 2-methanesulfonyloxydecane from 2-undecanol (30.0 ml, 144 mmol), methanesulfonylchloride (15.5 ml, 200 mmol) and diisopropylethylamine (30.8 ml, 177 mmol) in dry CH2Cl2 (240 ml). After stirring for 3.5 hrs, the reaction was processed as previously stated but at 4 times the volumes to provide 2-methanesulfonyloxyundecane (31.35 g, 95%). 2-Methanesulfonyloxyundecane was prepared

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The 2-methanesulfonyloxydecane (14.8 g, 62.6 mmol), 2,4,6-triiodophenol (29.7 g) 62.9 mmol) and potassium carbonate (8.7 g, 63.0 mmol) were reacted in DMF (210 ml) as per 2-(2,4,6-triiodophenoxy)-pentadecane except at an oil bath temperature of 72° C. for 88 hrs. The reaction was processed as for 2-(2,4,6-triiodophenoxy)-pentadecane to provide a light brown residue. Flash column chromatography (silica, hexanes) provided 2-(2,4,6-triiodophenoxy)-decane (29.1 g, 75.9%) as a white solid. to provide a light brown residue

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 2-decanol (5.0 ml, 26.0 mmol) in dry CH2Cl2 (52 ml) under an N2 atmosphere was added diisopropylethylamine (5.6 ml, 32.1 mmol). The reaction flask was immersed in an ice/water bath. After stirring for 10 minutes, methanesulfonyl chloride (2.8 ml, 36.1 mmol) was added via syringe over a period of 10 minutes. After stirring for 3 hrs, the reaction was diluted with cold CH2Cl2 (200 ml) and poured into cold 5% aqueous HCl (100 ml). The layers were separated and the organic phase washed with cold 5% aqueous HCl (50 ml) followed by brine (2×50 ml). The CH2Cl2 layer was dried (Na2SO4), filtered and evaporated in vacuo at 25° C. The resulting light yellow oil was pumped under reduced pressure for 2 hrs to provide 2-methanesulfonyloxydecane (6.5 g, 93.5%) as a light yellow oil. The reaction flask was immersed in an ice/water bath After stirring for 3 hrs The layers were separated the organic phase washed with cold 5% aqueous HCl (50 ml) The CH2Cl2 layer was dried (Na2SO4) filtered evaporated in vacuo at 25° C The resulting light yellow oil was pumped under reduced pressure for 2 hrs
