Dimethylamine → [(Benzenesulfinyl)methyl](tributyl)stannane

Participants

Reaction Steps

Phenyl methyl sulfoxide (7.0 g.; 0.05 moles) and dimethylamino tributyltin (16.7 g.; 0.05 moles) were admixed in a 50 ml round bottom flask, under a positive pressure argon atmosphere, for 20 hours at 100° C. During the reaction, liberated dimethylamine gas exited from the reaction flask through an open port with the moving argon gas. The crude product was distilled through a semi-micro distillation apparatus. The main fraction (13 g; 65% yield) distilled at 160°-170° C at 0.05 mm Hg. The product was identified by 'H NMR and infra red spectra as (phenylsulfinylmethyl) tributyltin.
