Heptane → Dimethyltin bis(2-mercaptoethyl caprylate)

Participants

Reaction Steps

Into a 2 liter flask is placed 204 gm (1.0 mole) 2-mercapto-ethylcaprylate, 200 ml water, 84 gm (1.0 mole) sodium bicarbonate and 300 ml heptane. To the above stirred mixture is added dropwise, at 30°-40° C., 110 gms (0.5 mole) dimethyltin dichloride dissolved in 200 ml water. Stir for 1 hour at 30°-40° C. and allow the layers to separate. The organic layer is washed with 200 ml water and then stripped under vacuum at about 100° C. A yield of 273 gm of dimethyltin bis(2-mercaptoethyl caprylate) is obtained. nD25 1.5060.
