Reaction Steps

Employing the apparatus and procedure of Example I, 100 ml. of an approximately one-molar solution of (N,N-dimethylaminosulfonylmethyl)lithium in hexane-THF solvent was added slowly over a period of 30 minutes to 0.1 mole of tri-n-butyltin chloride dissolved in THF. The temperature at addition was -60° C provided by a dry ice-acetone bath and rose through the addition period to 0° C. Following the complete addition, the reaction mixture was stirred for 2 hours at room temperature (20° C) and hydrolyzed by pouring into an aqueous one-molar ammonium chloride solution. Extraction from the hydrolyzate with ether solvent and purification by vacuum distillation yielded the desired compound, (N,N-dimethylaminosulfonylmethyl)tributyltin. The product, a pale-yellow liquid, had a boiling point of from 158°-160° C/0.1 mm. Hg. Analysis gave 43.8% Carbon and 8.5% Hydrogen compared to the calculated values, respectively, of 43.7% and 8.5%. The assigned structure was confirmed by infrared and proton nuclear magnetic resonance spectral analyses.
